Interview technical interview

Job Experience-Technical interview

This is the most important part of the interview: Technical interview. Applicable to computer-related positions.
For this part of the interview, no
There are too many skills to talk about, mainly depending on the individual's technical level, Accumulation Level and project research relevance. I believe that for those technically savvy students, it should be okay to pass this part of the interview. So the main content of this article,
It is to provide some specific interview questions to students with insufficient technical reserves. We hope that students who will participate in the technical interview can take the right medicine and make preparations in advance.
In general, there are two main types of questions in the technical interview: general questions and professional questions. For example.
(1) General Problems
General questions refer to asking questions about your resume's personal experience, research projects, and programming practices. This is an inevitable part of most technical interviews. In this part of the interview, I would like to remind you of the following points:
1. Projects that you have not done and those that you have not compiled Program Do not write your resume, because you will be asked during the interview. No matter how good he is in other stages, he will be eliminated immediately, because no enterprise can tolerate dishonest people.
2. You must be familiar with the content on your resume. You must be familiar with what you have done. It is recommended that you take a good look at the details of your project before each interview. During the interview, the interviewer often asks very detailed questions about the specific project you have done. Therefore, make sure that the content written on your resume is very familiar to you and you are not afraid to ask questions carefully.
3. When introducing your own project, it is best to select a job-related project, because for the technical director, he is concerned about whether the project you have done is relevant to them, and whether your professional expertise meets the requirements of specific positions.

Below we will summarize the common questions in this interview to facilitate your preparation in advance:
1. What projects have you done? A brief introduction.
2. Pick a project that you have done well.
3. What technology did you use to develop this project? What is the database used? What do you do in it?
4. What problems do you encounter in the project? How can this problem be solved?
5. What did you use in the project? Algorithm ? What technology?
6. How many developers are developing this project? How long has it taken? What are your responsibilities?
7. What third-party software/plug-ins are used in this project? What version control tool is used? What kind of software is used
Sending process?
8. How does the project implement progress control and risk control?
9. What tests have been conducted for this project?
10. Talk about your views on XX technology/field.
I believe that as long as you have done the project and the program has been compiled, this part should not be a problem.

(2) professional questions

This part focuses on your understanding of specific professional knowledge and programming skills. Interview methods include Q & A, on-site programming, and on-machine programming. General questions
Most of the answer formats are provided. companies like Microsoft, Google, and Moto will test your programming on site. Just a few companies that test algorithms. In most cases, I will ask you some basic technical details.
To test your knowledge of basic professional knowledge. Note: IT enterprises often ask more details. Computer jobs in non-IT fields are generally asked. The key to this part is technical accumulation, because
For many technical problems, you do not know. Therefore, it is very important to accumulate frequently asked questions and knowledge points for interviews.
Next we will summarize some common interview questions based on different technical fields. The source of the questions will be listed in brackets.

conclusion: This part of the interview mainly examines your basic professional knowledge and technical accumulation. So you must go back and read the key chapters in the book. Pay more attention to the accumulation of some common interview questions so that you can be confident during the interview and be calm.
suggestion: first, review the knowledge of the key professional courses. Then, buy a and take a good look. You must finish all the key chapters in the book.
. Here, I strongly recommend the to you. I have to read it carefully. when looking for a job, you will find that most of the interview questions are there. Finally, obtain the
story from the people around you, and write down the questions you encountered during the interview and the questions you encountered during the interview, understand it. In this way, your technical skills and interview experience can be continuously summarized and improved.
.
finally, I wish you all a successful interview and a satisfactory offer!
