Programmers are different from other majors. Other majors are older and more fragrant, but programmers are an exception. Because computer technology is updated too quickly and the work intensity is very high, most programmers will only write for 3 years. Code. After 3 years, you will either be promoted to project manager or change careers, except for individual research institutes.
What to prepare before the interview?
To be honest, I usually look at some interview questions when I am fine, so I go directly to the face (of course the process is very miserable).
I suggest that if you are preparing for an interview, you need to make the following preparations
背题Take a look at the recent face-to-face scriptures to understand what types of questions the company is dealing with now, prepare some common questions, and open the memory! If some basic js is not good, then the problem is a little big.算法To do some algorithmic problems, one or two Samsungs on lecode is enough. The front-end algorithm is very simple, and it is basically the difficulty of junior high school math.项目Project review, you must understand enough about the project you are doing from the technical architecture to the source code, at least not to be asked by the interviewer during the interview. And to reflect your role in the work, reflect self-driving. (Big companies are very fancy self-driving).亮点Prepare the highlights. When answering the questions, you don’t need to answer all of them, but there must be highlights during the interview (otherwise you will get feedback, and the interviewer says you are okay, but you haven’t done it~) I usually prepare a few points, Every point is guaranteed to be half an hour. In addition, you must understand it deeply and be able to express it smoothly in your own words! ! (Some points I prepared, performance optimization, engineering, caching, http)内推It’s best to find someone to push in, the success rate will increase练手First find a few companies that you don't want to go to (similar in scale) to practice your hands. If you go to the company you like for the first interview, the elimination rate will be very high.心态Mentality is very important. The interview is normal. It does not prove that you are not good, but you are not suitable. Summarize the interview experience and prepare for the next time.
How to answer the question?
How to say well about the problem that you know, this is very important
逻辑清晰It must be logically clear, or even if you know the answer to this question, the interviewer will not be satisfied. If you are logically clear, even if the answer is not, the interviewer will give you extra points.独特理解The current interview questions are similar, so how to show your strengths is very important. In terms of combining business and your own knowledge reserves.深入思考You must have in-depth thinking about each question, otherwise it will be difficult to enter a large company, and you must have a high level in depth to get good results in the interview流畅表达Interview is a process of expression. Some questions cannot be understood in the heart, and they must be expressed fluently. Basically, if the interviewer thinks you are expressing fluently, when you are halfway through, you will not be allowed to speak any more, and the proof has been passed. Up
