I. Introduction
this time a year ago, I started a real life job search process. In this process, the privilege to participate too broad embedded, Mindray, Huawei, Zhi Guang, Zhou, who, science, and several other large state written test and interview. While most have failed, but I think it is recognized that the failure of the first times I really understand their own shortcomings, gain experience, growth and progress, for the ultimate success lay a solid foundation. job is to show people a comprehensive strength of the process, in addition to professional skills, but also requires a certain strategy. and this was also a gradual process of improvement and adaptation. as a team to participate in a real game to go through the series of warm-up before the game, familiar opponent Also found wanting. then I look at other people's decks by now I think his own experience to share with you is also a very pleasant thing. especially at this moment looking for work in the climax, I hope I've Summary of job experience and help give you that reference Oh hh
two widely embedded in the interview
This is my first formal interview of life, very nervous. widely embedded in the side of the Guangzhou Science City, a little way off , relatively few people. The first is to do questions, there is no time limit, finish on the cross. subject much, if 8, all questions and programming questions, did not have to Mongolia. major test of the C of voice, data structures, operating systems , compiler theory, memory allocation and list some of the things. Although it is very basic stuff, but do not usually pay attention to it. topic done, HR take the matter to Chief Technology Officer of view, to tell me after a while, technology Director, my answer is satisfactory, told me to go the conference room for an interview. Technical Director to be a relatively young engineers, conversation between the feeling of huge cattle. I first introduced the situation of the project, may be the first bar, talking about the comparison Fine, he listened for a feeling that I actually did something, too lazy to listen to me, direct me to stop and began to ask me a few questions. does not look any technical problems, but it works out. I'm impressed profound is the following three topics:
1, in the school lab program to do the actual programming of projects and what to do different projects, you need to pay attention to what?
2, if the company ran into administrative problems and technical difficulties should be how to deal with?
3, your career or how to plan your future years?
these answers matter of opinion. I did not think he would ask these questions, start stunned for a few seconds, the brain about turn, however. but I'm relatively satisfied with their answers, technical director may agree my answer. Then he asked me to do TCP / IP side of things how. I said no Zenmeyangzuo network infrastructure had something major to do the application layer above the socket programming. Then he asked me in windows and linux the driver layer and application layer have done something, I'll talk a little work-related projects, and said one said. Then he introduced me to come in company to do some work, mainly to do TCP / IP application layer testing and validation work. back have nothing to ask. He went out after, HR came in and I talked about the company's specific circumstances and welfare things. about three hours, my first interview so the end.
three Mindray Mindray's written receipt of written
actually not very surprised, but quite unexpected, did not think the day began to proclaim the written completion next afternoon, There was no opportunity to prepare a little, to an eye-opener it. Mindray informed me to take a software engineer, but I know C + + is not so, certainly have done nothing. Fortunately for the people and to King face hardware engineer went into the examination room . I have to go after the title of research engineer the system, that system is not very clear what the specific, or can talk about ideas. However, the exam is too much of their combat, and finally really see the level of their the.
title in hardware, a wide range of test, mode digital circuit, CPLD, operating systems, algorithms, intelligence, design and so involved. on the fight against their own is clearly looking to know how to do it But forget the formulas related to the concept, can not write, even more sad is that careless mistake would do, alas ... hopeless.
Question 1 is a unit conversion, I actually put 1Gbyte = 1000Mbyte , out of the wrong think to know, should be 1024. Question 2 is a model of electricity subject, examine common-emitter capacitance of transistor cutoff frequency of the upper and lower cut-off frequency effects, including the coupling capacitance, interelectrode capacitance and wiring capacitance. Question 3 was asked what Moore's Law, Moore's Law have any effect on the hardware development? I can not write a word down. Question 4 is a sad topic and it is the only one I have a little grasp of the subject, to the two op amps, asked to write the name and expression, a differential ratio is the amplifier, an integrator circuit, but due to carelessness, the derivation of the differential amplifier to push the wrong ratio. The next topic is what ..... . The first 5 items usually do not, the title is that when high-frequency capacitance can be equivalent to an inductor, a capacitor and a resistor in series, and asked what practical use when doing the right frequency. The first problem is that the number of power 6 the subject, what is the adventure and competition, how to eliminate risk and competition. the number of basic topics of electricity, I was blank, you said I can not do this subject to, blow on a resume you are familiar with electronic and digital electronic modules Some people would believe it? The following is the English translation of title subject to a PCI read timing, let you translate the above in English translated into Chinese. then an intellectual topic: a city from the A train to the train station after work His wife just ride from home to home station to meet him one day, he sat morning train, went to the train station at 5:30, and then walking home, his wife took him half way back home to find 10 minutes earlier than usual, and asked how much time he sat way? this question I hung up. followed by the optional problems, 3 1. a model power, to the op amp, diodes, a front-end signal AD conditioning circuit, to find out the error. Well, not any clues, it is estimated that the diode clamp, wrote a few words. Another is to use the CPLD language to describe the JK flip-flop, JK flip-flop and then with the non- Door Dachu D flip-flop. This question I gave up. The last one is the subject of the operating system, on the PCI bus to read the way the three, only to give up. Oh, and there are a binary tree traversal program added, Oh, this is the most fundamental and simple data structures subject, I was disarmed. should be the last question, and tell you a successful project or curriculum design, draw the block diagram, say the working principle of touch to how to solve any problems. This, of course who will be writing to pull Well not to brag.
look at the systems engineer the subject in three parts. The first part of the four optional subjects, and the company's four product closely related lines, the first is to describe the characteristics of ECG signals and methods of measurement. The second is to describe the characteristics of physiological signals and measurement methods. The third is to talk about the characteristics and implementation of digital filters, the last one is to talk about the principle of spectral absorption device like. thought that the third is familiar, but do not know how to write, well, anyway, will not, the election of the first to blow a pass. The second question is a programming problem, one is added Han Nota procedures, as well as part of the bubble method to calculate the number of comparisons and the method used to find a maximum value of the order of the average number. Here a subject is a design, design a digital camera, from the market demand, functional design, quality, to design feasibility and market risk. Fortunately, this can write something, or is that has done nothing of the. Finally, the subject of a 4 to 1, test the accuracy side of things. The first is to talk about the accuracy of vernier caliper factors The second is to analyze the accuracy of CNC machine tools factors, and the third is to analyze the light intensity of accuracy of measuring devices. The fourth forgotten. I chose the CNC machine tools that thing wrote a few words.
Although is deeply received a blow, but really see their own level. learned so many years, things have not mastered the most basic, is ashamed ah. It seems a good time to start look for their own direction, and clearly a went to go and review goals. software are something I know fur, it seems, and it was never meant to pull points, and the outstanding bonds of the hardware seems a little bit ah.
11 月 Supplement No. 1: Although there is no opportunity to interview , but still concerned about the situation Mindray interview, recorded some way seen in the Zhejiang University, Zhejiang University BBS cow's face by:
interviewer is the day of invigilation staff, see also his papers. if he is According to an interview test situation to be content. never to talk about his problems began it:
1. you choose to work in Shenzhen, Shenzhen has considered closer to home?
2. If the boss gives you a hurry to tasks, logically speaking, to 7 days to complete, but you have to be completed within 5 days, how would you do?
3. you have such an old engineer around, he may not be as you are powerful, but his temper still well, how would you get along with him?
4. your boss have a set of programs have been identified, and soon to be implemented, and you think your program is also good, and also very innovative at some point, you will how to do?
5. you choose to do something special in mind hardware?
6. I think you answered the last question in detail is also very neat, is the result I wanted, but I want to you explain to me the key to problem solving ideas. he will give me a piece of paper in my frame interrupted the process diagram, by the way, several technical issues, such as the comparator op-amp to do and know there comparator What is so different points.
Finally, he said it might not be a second interview, but the morning of November 1 will determine whether to offer.
my feeling is: A free play of the title last time, We are most familiar with the best project their own write, and write clearly, so that people will leave a good impression. Another project, if not own, or interpretation of unclear, not to mention the best resume, be they Eyeing not easy to say. But they still very Nice's.
IV, Huawei written
people are right to do things, not only have goals also need to be fully prepared. Although I do not have clear objectives, but this time I had a little preparation. Mindray hit since it was me, I know myself again. back to review a bit serious homework.
While Huawei's hardware very basis of the written questions, But I also have a lot to do well. but at least the failure can be a little Mindray a little restored confidence, no matter how kind the results, I can finally finish from start to finish, also handed in half an hour earlier. Here a little summary about it.
for Huawei, I feel people are very dismissive of cattle Zhejiang University. BBS concern to many people above, there is negative news Huawei. Mindray has four classrooms were written that day, Huawei also a daytechnical service class. But I heard the treatment of R & D Technical Services analogy to Ay. in the examination room, nothing of the check, go to test, without notice to you can test, in short, he told Reuters.
papers has 10 fill-in, 12 radio, over 12 elections and an analysis of problems. which analyzes the problem is called to write the truth table for decoder 2-4, is not it even more simple than the final exam, 20 points oh . fill in the blank first op amp is a subject of a number of known conditions to find the op amp's output resistance, came out to listen to discussion, if I be wrong. second and would not, ask what is keying 2DPSK is communication aspects, in the Baidu search, I had two points difference between the phase shift keying. What is the bit error rate below ah, what a group of PCM, the 8086 register are a few, give you a static RAM and 128K start address, and ask you the last byte of the address, as well as VHDL and digital logic and so on. have a question no less than what I wrote and asked the logical combination of the output clock used as prone to do. Examination of the multiple choice or based on things that have asked the IBM-PC and compatibles of the I / O port space, PCM32 a group of a complex frame of time, there is the question symbol long 0.1us, 2.5 秒 produce a bit error, the error rate is the number, not will mask it. also asked about the difference between RAM and ROM, static RAM and dynamic RAM memory cell structure and so on. multiple choice compared Transformation. the first question must be asked the following logic gates up resistor is: OC door, OE door, OD door, above all things. The second question is to ask you the following is the programmable logic device is: ASIC, PAL, GAL, FPGA, CPLD. The third problem is the difference between RISC and the CSIC. The fourth problem is the bus function, I do not know the function of the bus driver is not, so no choice. fifth title a bit difficult, ask the following to avoid the competition and adventure are: synchronous sequential circuits, the use of asynchronous sequential circuits, state transition table modified to increase the delay logic. Sixth is the difference between ROM and RAM, the following is the 8051 P3 pin multiplexing function, then the composition of the detector, there is a common filter. The first 10 questions will not: ask 8KHz and 10KHz sine wave through the mixer After those who can produce the following frequency signal:-2K, 2K, 18K, 1K.11 test 8051 interrupt question, the last one is not easy, ask the following two negative feedback is right there.
from the difficulty of the subject and breadth of perspective, Bi Mairui simple, but not for people who've been out of difficult to do Oh, wide, heavy base, the key still hateful multiple choice options. Overall, the performance of my own quite satisfactory. no Mindray so embarrassed. but not below the estimate. I think people who do well in this subject is ah great. Listen to the morning received a phone call, and said, Huawei is mainly engaged in the hardware aspects of 3 : DSP and algorithms, logic, ASIC. Well, I do not have one of these three will, let alone understand. even into the side of honor, will also be brush, I think the main impact or professional is not quite a bit.'s future things to talk about it and so it happened. well prepared for what is the right way in front.
V. Huawei Huawei hardware side
feel good after the written test finished, and she got the opportunity side. but we go to school written examination can go to the interview. But I heard this done Huawei hardware DSP and logic only two aspects of recruiting, I feel a connection to the journey of the termination of Huawei to see big long interview experience it is . My interview time was arranged in 6 of 9, the day 6:45 get up and have arrived from Huanglong Xiasha side of a hotel, extreme pain.
do not know how to engage in, and I together and have a few 9:20 of the interview has not yet finished our turn. then ask the group know that I arranged to go inside the DSP, then quickly call them to logic. probably wait until 11 o'clock, and finally to me . But when I went to the front of the official launch, he said go to the bathroom and told me so a few minutes, it appeared that really frustrated ah.
interviewers were very friendly and polite, we say hello, I feel loose tension a lot. Then he began to aim at my resume, I estimate a little, not more than 3 seconds. good thing I do is a resume. he saw me behind the two items of physical map, pointed at me In the 2004 winning machine design contest asks: . but he does not seem interested, and then asked: Although there are related courses, but we learned a number of entry as long as the basis for practical applications are still far away from, when I was undergraduate major is learning some basic knowledge of the system, mainly at the graduate level with the teacher doing the project, In fact, the skills I am now and I do the major project-related, on the basis of the previous two aspects of one of more in-depth study. more Well, we have to do SBC software, it also uses some small CPU and AD conversion, DA conversion something you are willing to do that? life, and quickly said: while glad I finally resorted to the weapons.
the following interview in full accordance with the contents of the direction I anticipate a. First, I detail the system I brought from the principle to the diagram, from performance to key point that a pass. He listened, asked me: project, the system has been designed well, and I do is to test the old version, improvement, from the perspective of hardware and software to improve performance and stability. He said: to ask you a few questions? what a diode is used, I said it was the protective effect, mainly limited current reflux. he was a very strange, he said, limiting the role of the diode does not seem right, I think he might got it wrong to add the diode Continuity of single guide, round a bit field. Then he told me to be active filtering system drawn above, over, the system I do not understand that place. how do? only painted it, drew from memory a second-order active filter circuit, told him that I actually forgot about that so be it. He said you talk about this filter works, and I do not even draw are drawn out, the principle is more ambiguous about the . I told him: speak more clearly to pull. He asked the last question, if you have a long line of the sensor, your system will have any effect, I also answer according to the approximate direction of the pull, I'll say this signal attenuation and interference caused the increase. He paused a little and asked if I like to do a little more rigid or soft point. I said, relatively speaking, I usually do a little on the soft things more. He said: subject.
first: Write a macro called MIN macro, enter the two parameters, find the smallest one? fainted! I met many times, but why is it in that time forgot? but can not say Oh, no, people say to me to find a simple. just bite the bullet and pull to write. My answer is:
# define MIN (A, B)? (A> = B) B: A
He looked at my answer, quick to point out a few of my mistakes, it should be:
# define MIN (A, B) (A> = B)? (B): (A)
second is Reading to write results in a mian () function calls inside a loop 3 times a function of the static variable, the output of a, and the results. this I am most familiar, and San Liangxia put the outcome and process and privations. < br> At this time, almost to the end of the interview. interviewer asked me a workplace issue. I said I was Cantonese, like Shenzhen, which he said no problem. and then I work a confirmation of my content, he said mainly soft bottom bar, and then when the time allocation between departments, and he looked at my resume, I found my experience with ARM, and LINUX, and he said that in fact they will do something related, such as VxWorks, etc..
At this time, the interviewer told me that he was satisfied with my ability, my heart burst of ecstasy, pride or pleasure do not know. he took the initiative to stand up and shook my hand, said the Secretary told me to such notice, notify the next round of interviews In these two days will be issued. Then I do not know what they are doing, and pick up my stuff the next, before he shook my hand again to take the initiative and the interviewer, thanking him for the interview and guidance.
six Huawei Huawei did not expect the two faces
work efficiency so fast, originally thought to have two faces to 8 notice, so playing a 6 pm to go to sleep until 1:00. When I was fast asleep time, to two text messages, and my heart burst of rage, half past two texting someone so boring ah. But a look at the original notice of Huawei 9:30 am 7 good interview, and sure enough, and we say, and the collective gang fights PK, regardless of it, continue to sleep. otherwise sleepy to 7 points up, but around 6:20, again the message, or notify the interview Huawei, they do not work overtime to overnight it.
to our school to participate in research and development side, there are 4 people, including three went into the second interview. to the designated hotel, first fill in a form, really is more, what had to fill. had arranged a 9:30 interview, then dragged the 10 20 points or so. Before our group of 12 individuals to almost the same, we first get to know quickly what, to the time when PK is also more familiar with the thing.
time, we led a MM into the room, three tables arranged in triangle in the middle of a card is 4 males and 1 female interviewer. the two groups outside the two are AB, anyway, we casually sitting, 12 people were divided into two groups of PK. First, each person a piece of paper folded nameplate, and the candidates will post their names written on it. Then the interviewer started calling us introduce you to say to the interviewer and left a deep impact on you, about your characteristics and future career planning. I Zhejiang University who found the ideal Oh great, career planning, technology management is what to do with the professional managers. I have forgotten how I kind of introduced me, as if to say that some of my winners of the competition and said that my hobbies, like playing football pull, I think there is more solid basis for my hardware, which can play a director of Huawei, reflecting the values, Huawei is a big business, I can get exercise in there and grow. do not know that there is no problem?
then begin an activity, which in 10 minutes, each subject will be issued according to which are most worried about what white-collar sort, and then by the group of statements inside the grounds of a person, then other people can complement. Activities At first I put a view, but the views of a man better than me, then do it according to his opinion, and I nominated him for the advantage of the opportunity our group leader. in 10 minutes inside, HR We have come to see the performance, then score, anyway, I do not how to order, I just look at all the action coordination, ah, ah look at the time. Soon the time came they were the first group of statements, the statements in the process , the interviewer will interrupt the statement, called another person to add statements. Our group is. In this presentation, I basically have nothing, be the least of the words.
order of two very different groups This time interviewer said, the reasons you stated the two groups, respectively, so that the other party agrees with you. Then, two groups of people to have to show themselves in this process, I almost without a word, it seems committed The taboo of the gang fights. Finally, the interviewer asked the students not have spoken from the Laiyueliangju, I am the last to speak, and I will say that two points summary, and then rest for 5 minutes.
In fact, 5-minute break is to exchange our two groups on the outside look, unified look point of view. I know him, came out I asked the two groups is not what should be a unified point of view, ah, if they feel there is no step backward, and that even if of the bar.
soon have entered, the first interviewer who called each other a group together, talk about his views, he said, agreed to a point, but our group there are different places. After he finished the interview officer looked at me and said, you seem a bit out a unified point of view, you talk about 12 points to top Group B side, you think you do not agree. I suddenly fainted, how to answer it, and the answers agree Well, do not know Our group will not be identified, said, say no identity Well, the interviewer confessed that our unified views, and group B who also compromised. that I only used to find circuitous tactics, the content along the B group have just said something Summary of things, neither agree nor deny recognition. interviewer to see I deflected the question, in turn question again, I turn to the side just saying. fainted, then that side official to the sentence in fact, I just ask Do you think do not agree, I found this time leader of our group wrote a paper in recognition of my word, I hasten to say that identity recognition, which can sit down ah.
then is the PK time, I think our group The only participation. B group also had a person, the interviewer said, to give you an opportunity to you the features and advantages you say it, so we think you should join Huawei. ah, said the other man said, let him give the interviewer a case. Little did I know it's my turn to participate in the PK, is not because I would too, not positive enough, or what ...... I'm a little nervous to see the interviewer, said to me, you see me now gives you such a good opportunity, you want the features and advantages you speak out, others I have not given the opportunity ah. do not know the words to comfort me. then I say slowly, I am relatively easy-going personality, like to communicate with others, I feel that the process of communication will be greatly improved, compared to my basic knowledge of solid practice in the project, found that basic skills is important, many high-end problem-based knowledge can be used to resolved. said I was learning the hardware undergraduate, graduate school is the software, in practice the process of discovery begin now, no matter the hardware or software is a collaborative process started, you can not split the two machines that I consider the problem From a systems perspective to analyze the individual is not necessarily the best, but may contribute to the system is the largest. Finally, I concluded that the advantage is that I am a man of my easy-going, independent analysis of problems and problem-solving skills, self-adaptation and learning ability is stronger, in the knowledge structure of the above, hardware and software, the actual project experience more. interviewer then asked what I usually love, ah, I said I like sports Yungong, especially playing soccer. He actually asked me play that position, do not know if he can play football, I was in midfield. He asked who and what I usually have to play ah, is not and students kicked, I say not, and students sometimes play, sometimes to pitch, hit and who will come to play, and that I participated in a large football.
Huawei to this legendary gang fights over, although not put it online terror, but I am led a little bit unhappy, and do not know the reason I was asked. after that there are 10 minutes question time, Huawei was asked to resign collectively and overtime issues, as well as following some of the arrangements. then I knew followed by a single on-one interviews and the overall quality of comprehensive testing, personality test and English test.
long way to go ah ...... do not know if I can receive notification of it on three sides? so it ......
VII are very grateful to Zhi Guang Xie Zhiguang interview
electrical pull me the opportunity to interview. As noon, 18 graduates of schools image data to be collected, I can not participate in the written test Zhiguang Electric, although the day and in the teach- prodded the relevant staff, but until that day more than three in the afternoon have not received any notice, in Zhejiang University has already been started 88 to see the interview, and feel this is not another game is it? altogether forget to go back to bed dormitory . when actually received Zhiguang Electric phone, what time that day, 8th Floor, Hangzhou Bainaohui interview ......< br> written and side did not participate, directly participated in 19 interviews, so that the treatment I the first time, the feeling is very respected. have the opportunity to not miss the rest of the time I started cramming, I heard that useful, but the interview I did not spend the time, because I estimate will interview a few 10 minutes. I waited for about half an hour before.
interview I was a PhD, and another three people. mainly casual according to your resume to ask you something, but each technology is very to the point Q on, but I also answer on the very point, and very honest, a lot of things I did not design or direct that a person I do not, perhaps down so they are no longer asked. now we all know Master What level of tension ...... can not say that he is a big cow, guess I said sure not escape their stuff. this time I still had my graduation project with the board to do the past, but they are easily looked at, it did not say anything, I do not have access to play ...... is not that they despise? They ask why do it using Winbond MCU? I say cheap ah. so. In addition asked me if I have not done the motor side of things, I put the previous guidance of mechanical design and electronic design competition contest something to say, around five or six words on it. Later, someone asked me to do a data collection What the telephone network drive letter, I said MODEM, that meal would have thought I could pull large, that engineers say can, and know. Then I have nothing to say. basically talked interviews are some basic issues to end.
next to talk about treatment, and that the main surface of the Dr. asked how much money I expect, after several blows, and I am sorry to say, say I do not have very high demand, medium can be a . He told me Just tell me. I said it 5K to 6K. He said there should be no problem 5K. It is estimated also that worth. Later some of the work content and chatted for a matter of time, it should be very desirable. and then call me for three. I said to reply within two days. I was too tired to find a job too time-consuming and energy, and it is no choice, it is so ...... go back and think about it, sell it.
Pat, the rationale for the state since the last interview after completing the interview at Zhi Guang, there is no suitable unit arrived. In Zhiguang interview finished, I was ready to sign the three parties, their HR told me to wait for the headquarters of the Chief Engineer, Guangzhou Phone interview, but nearly two weeks of no audio, it is estimated I was they gave up. just 1 state to Zhejiang University, Shenzhen Li preach, and went to take a chance now.
immediately start day End of the written proclamation, before better hold the next Buddha feet. I am applying for the original embedded software engineer jobs, need to test a software problem, but the thought of software algorithms, was a little Huang Huang, subject to the copies of the hardware to do. topic much, Pat nine short answer questions, mainly related to the transistor, op amp, filter, trigger, AD, communications, microcontroller and some very basic things. I have a body exam by a hundred people, each company's topics are about the same hardware Most do it without any problems, except for a voltage-controlled current source and the subject of a FET did not do, the other problem is not large, estimated to be below, and sure enough the evening received a telephone interview.
state company management First you ...
