This series last one considered changing jobs, mainly want to talk about the job search process some thoughts, such as the company's views on education; some companies interview Why is relatively interview made bomb, entry tighten the screws? And my understanding and views on these things.
Two interviews experience
when you are ready to change jobs actually have interviews with several companies, including big small, as well as direct remote telephone interview can handle, as well as on-site interview. The beginning of the interview, a company is Dahua, that is to do security Dahua, at least while playing into a telephone interview written test + + round two on-site interviews. Telephone interview basically do anything you ask project, a general description of the contents of your class project, I've encountered are of this type, the main purpose is to see if you should really have done is not something that can say 1234, or else we would not have to waste time and energy on-site interview. Telephone interviews do not focus on description, as are similar, except for one, I'll talk about in particular.
Dahua
Telephone interview did not say, is to ask skill tree, projects done. On-site interview, then give you a pen questions, questions the pen strokes of the content seems almost like school, maybe they put me in accordance with the standards of the school recruit to look at? Or is it written that these routines. There are basic things pointer arithmetic, multi-threaded programming problem, list sorting problem, variables are stored in memory, basic computer concepts.
Written examination which is more difficult, I think there is a problem to sort the list, hand-written code you need to come out. Other white after working for a period of time, it is not difficult, after all, only the embedded topics, the complexity of the algorithm is not very tall analysis, such as handwriting spot a heap sort, something like KMP algorithm.
Because of security will involve transmission of encoded video data stream, middle and asked some basic concepts of H264, before I have to know some, but the concept of a site to ask I do not know, because the basic work usually does not involve the processing H264 stream directly said no, then the interviewer to ask the project according to the contents of my resume, it must be emphasized here that he wrote up the project even if you are not used as the backbone, but also must ensure that everything on the inside are aware of very thorough.
My experience is concerned, a large part of the time, to do their own things that are part of the overall project inside, and often only concerned with their own little plot, basically did not go through the whole project or no attention to the effort of all covering it again, I think this is a relatively lazy behavior, because all the line and again really tired, but I think it is necessary, whether it is for the contribution of this project is to enhance their ability in terms of are very good.
The first round behind the interviewer asks the question and replaced by another interviewer (first looks like a department head), and the second looks like a technical director or technical relatively good man, he let me up introduce an item from his past, the more detailed the better, so he is a new introduction, and then he just asked a question: What's more write code, or more solution BUG? Pick a Laijiangjiang. I said recently de-BUG more, so pick one, I think involves a wider, more difficult problem to solve in detail. I think this process is to look at your level of understanding of the content of the work to master, see if you can say clearly whether logic can straighten out and if you have your own opinion.
The next step is the HR side, is designed to allow you talk about why change jobs, ah, ah expected salary, there is no more want to know what ah, etc., more conventional, society stands to reason that attracted talked about this step is considered a relatively stable It is not it, but the next day I received a notice that was a pass, then look ignorant force, because later on the interview process has been re-set, and no poor place, later thought to be due to expected salary question, but I did not fine to ask, because to go Dahua subjective views are not very strong, as it is an exercise, after all, since the school recruit, has for some time had any contact with the interview, somewhat routine for some rusty.
Outsourcing companies
I remember there Soft International, a hundred CHANCE, ArcherMind, the Branch was a big ticket companies and so on. Do not know the beginning, later found raped, many are outsourcing company Huawei, Huawei and some specialize in outsourcing, some departments do certain Huawei outsourcing, at this point had to pay tribute to Huawei, Huawei a company driven by the number of peripheral industries, to feed the number of people ah. And there are a lot of outsourcing companies are listed companies, it can be considered more of a class of cattle Cup.
Specifically which company I forgot, there were only a phone interview, asked me a question, is this: pointer and array name What is the difference? According to my own understanding to say it again, then the interviewer began to ask other questions, such as what kind of exercise you like ah, usually have a hobby, and so on. I am a bit curious, I ask interview this end? The other side says yes, you see when you come here to work? (Because there are HR salary before what gave an approximate number).
Well, that I do not dare to Kazakhstan, because I always give a more casual feel, though I was hired to recruit school course it is very casual magic, but after all, school recruit, did not have much choice. I feel this is very sloppy, the key to this is not important, I am not very understanding of each other's culture, technology and so on, so I do not make decisive practical, if I and other cooperation for a long period of time (technology cooperation and the like), accepted by both parties, then I would not care that much.
In short there will be many outsourcing companies like are basically the kind of come directly to you, I personally do it for various reasons, do not like to go to outsourcing company, may not be so exaggerated, but I might by network for outsourcing firm views on the impact that this is no way, so this type of companies have since been dropped, no longer being considered.
Qualcomm
Qualcomm, then the beginning is the relationship a headhunter to, position the beginning is AE / CE posts, thinking, after all, is a high-pass, you can take a look at the situation, so early in life through a phone interview, then about to go over there live weekend interview.
Would have prepared a pen questions, beginning after the interview to ask a lot of questions, I personally feel that for technical direction is concerned, this is very good interview process, ask more in-depth and meticulous. The final written test did not let me do, may feel no need to, meaning they probably less the same level I have learned, can also feel, no need to re-written.
But I carefully asked the specific content of the work the other side of this post, I think it is not the last stage aspire to type, so although Qualcomm, but I have no choice in the past, give up this opportunity.
Then later, the search may think that this guy also seems to be technical, it has pushed a job RD, originally I did not intend to go for an interview or something, because at that time I did not want to change job, but later Yin Yang poor wrong for some reason chose to try.
Qualcomm had several rounds of interviews, a written test, I feel it difficult to pen questions, recursive, C ++, pointers, multi-threading, dynamic programming (you're not wrong, that is, dynamic programming), C basic concepts of language and so on. Topic managed to get quite detailed, I do not have a lot of definitive answers, some will not, for example, as well as the most dynamic programming C ++, and some because of too much recursion, I'm not sure artificially calculated the result is correct, but the idea is to determine the.
Interview several rounds of bombing catch the foot is not very good, because you have to repeat over and over again to answer a lot of questions, which resulted in the latter state of mind may be unstable for some more in-depth problems that may be due to irritable heart and error. This site will have several interviews handwritten code, an oral interview each round there, but I basically written down, to include: a linked list basic operations, basic string operations, simple ordering (fast discharge) and so on.
RD is a difficult job interview I've ever experienced relatively high, I feel more of a dry interview experience, still quite helpful, I am now because of vocational high school on, the interview also do not want too much more detail described what.
Views on education
no matter what industry, education is always a very important corner, which determines the starting point of your limit, and largely determines you can reach the heights, I passed the school to hire views on education have now some changes.
When in school, because I was a college, be able to meet the minimum requirements of the job market nominally above, I heard a lot of big companies will recruit card education before school, I was very disdain, are top schools there will be no school slag yet? Why so unfair to our school students a little time.
I later view has changed, basically it boils down to the following categories:
- High quality than the average student in school almost good schools, good schools company perspective can reduce recruitment costs, including the cost of training and so on after the screening and follow-up entry.
This has been largely a consensus. - Good schools rich resources, including teachers, equipment, funds and so on, while good schools around there will be a large probability of a lot of good people, that is, good people get together there is always that you recruited one of them, may It will bring more people (good people) added to the company to go, and then form a positive feedback.
- Better educated high probability indicates that this person's qualifications ability is absolutely no problem, it will be more open on his big probability awareness than other schools, comprehensive, resilience and self-correction capability high probability will be stronger.
- It can be admitted to the school a better person as it should receive better resources, and why?
Is not that unfair, if a high probability graduate starting salary higher than undergraduates, like, what to read because he was a three-year graduate student, wages higher than me?
I understand that people pay a high probability of more than you, people show up on the part of the objective conditions better than you.
If you are really gifted, but the school still born bad, probably because you volunteered error, probably because you just awakening after entering the university, probably because the objective conditions and so on and so on. Then feel they have been treated unfairly, this Tandao me if I think so, would not understand.
But I think for the most part in terms of, you feel not well educated subject is very illogical unfair treatment because of your illusion, or that your perception is not caused. Higher education, representatives of large probability greater learning ability, better world knowledge, better social resources, greater self-repair capacity upgrade.
Step back in terms of, if it is indeed very fast hardware, but in any case, has a relatively low starting point, then please do not give up, do everything you can possible go downfield, there will be a good return to you , I am sure of that.
Why do some interviews and some did not like to ask
I think in addition to the interview visit our technical capabilities, more is to examine your own person, including thinking ability, personality, cognition, and so on.
Ask some work basically less than the data structures and algorithms, you may feel uncomfortable: This is what the hell, my work will need to use this? I can provide a perspective on such matters, although it is not necessarily right.
Ask those things, if you're interested, do not feel very nonsense, and answered it (most of the time will not be difficult), it is not this person may think you closer to the interviewer in character, thinking? That possibility you will be able to achieve good cooperation is not to be higher? If you think the problem is too crap, it is not explained to some extent does not match your personality and atmosphere of the interviewer or the perception within the company? That is not likely to reach this level of cooperation than good?
Moreover, according to my observation, those who do not think these things usually work above nonsense is more able to toss, and the answer can be extended to more people will have a lot of details to work better than others at the top. But this this is my experimental conclusion, completely does not mean the fact that you can think I'm crap. Some may seem unrelated to technical things, will help to understand a person's character, so as to achieve the purpose to find the right partners.
The above is a perception that I summed up as candidates, initiate purposes only.
