We have previously shared job introductions, job search preparation ideas, and how to prepare resumes. Today we will talk about interview skills~
1. Interview process
Let’s talk about the basic interview process first: Resume/written test screening->Technical first interview->Technical second interview->Technical third interview->Technical intersection interview->HR interview.
There are several points in this process worth highlighting:
- Technical initial interview: This is the most difficult aspect of the entire interview process, with the highest elimination rate and the widest range of knowledge points examined. If you can pass the first interview, it means that your technical ability has met the basic requirements of this company. The subsequent interviews are to select the best among the effective recruitment quotas.
- Technical second- and third-level interviews: Of course, it is not ruled out that there are only two-level interviews or more fourth-level and fifth-level interviews. However, compared with the first interview, the difference lies in the higher level of the interviewer, the narrower scope of the interview, and the depth. Deeper.
- Technical intersection: There is a high probability that this does not exist. If it does, don’t worry. It is often because the interviewer is not sure about your direction and needs more qualified interviewers from other departments to help evaluate it.
- HR aspect: This is a non-technical examination, mainly focusing on personality, expression, stress resistance, etc. The difficulty is average. As long as you don't make low-level mistakes, it's basically fine.

2. Interview scope
The interview scope mainly includes three aspects:
- Focus on the projects on your resume and examine professional skills and problem-solving abilities. This part accounts for 50%;
- More knowledge inspection on professional skills, which mainly covers: data analysis/processing skills, use of data analysis tools, inspection of necessary SQL for data analysis, discussion of data analysis cases, and machine learning-related abilities. This part accounts for 30%;
- The general ability test is divided into probability questions that are unique to data algorithm positions, logic questions that are commonly tested in all walks of life, and coding questions that are commonly tested in IT positions. This part accounts for 20%.
It is worth noting that if the projects on your resume are too simple, you will not be able to pass the interview unless your basic knowledge is very good. In addition, if the project and professional skills tests are both good, it doesn’t matter even if there are problems with the general test.
If you know the main scope of the interview, students will have a general scope when preparing~
3. Interview skills
Regarding interview skills, no matter how fancy you talk, you still have to rely on hard skills, so students still have to work hard, learn knowledge points, and systematically understand various technologies. The skills I can summarize can only help 10-20% at most. Of course, I will also sort out the entire knowledge system in the future and lead the students to improve their hard power more efficiently.
Let’s talk about those interview skills that are the icing on the cake~
In the final analysis, an interview is a process of communication and dialogue. I have summarized four principles to share with you:
- Know it well: Before participating in the interview, you must be aware of all the knowledge points on your resume and the knowledge points that are likely to be developed. This is the lowest and lowest threshold. The second is to have a clear understanding of the professional knowledge of the entire position.
- Appropriate detail: An interview is a conversation. When answering a question, you should first answer the core of the question directly and briefly, and then expand on the details one by one. It’s best to keep each answer no longer than 3 minutes. Don’t let the interview process become one where you speak alone while the other party listens. Pay special attention to the fact that when you feel that the interviewer is interrupting you, it means that you are speaking too long. Be wary of this happening. But sometimes there are indeed a lot of details that need to be expanded upon. What should I do? Then you have to give a certain summary. After you finish speaking, wait for the interviewer to ask him which part of the details he wants to know more deeply, and then you can continue.
- Stay Calm: Everyone knows this, and if the problem is within your range, it's easy to do. The difficult thing is that when the question goes beyond your knowledge, students will easily panic and stutter when speaking. What you have to do at this time is to tell yourself to calm down and think about this question. If you can guess and try to answer, you can say, "I didn't know this before, but from my inference, it may be XXXX's solution." . This is like not knowing the answer during an exam. It is better to guess the answer than to leave it blank. At this time, if you answer correctly, it will be a big bonus, which shows that your ability to draw inferences from one example is very good! If you really don’t know, just tell the interviewer directly that I don’t understand. Remember the situation where you spent several minutes grinding and finally couldn’t come up with anything.
- Take the initiative: This last principle is the most important, and of course the most difficult to master. This requires continuous practice and understanding. Many students will encounter this situation: XX interviewer does not understand my project at all, and they all ask irrelevant questions... This situation is because you do not take the initiative, and the interviewer does have doubts about your project. If the level of understanding is relatively low, then you must first describe the problem and plan clearly in an easy-to-understand manner, and then be good at guiding the interviewer to ask the core questions of the project instead of letting the interviewer wander around the edges of the problem.
In addition, I will talk about two questions that 100% will encounter. It is strongly recommended to prepare the answers to these two questions in advance:
- Self-introduction: Remember not to be too long or too short. Simply state your name, age, educational background and graduation date. Do not expand on the projects. Instead, mention a few projects on your resume. Finally, "Which project do you prefer?" If you are interested, we can talk about it." This sentence is an example of taking the initiative, which means that the next sentence the interviewer wants to say is based on your suggestion.
- Let me briefly introduce the first project: the idea at this time is the same as self-introduction. First, describe the basic information of the project, focusing on the problem to be solved by the project, so that the interviewer can truly understand the problem. After that, let me briefly talk about how I solved this problem in steps 1, 2, and 3. Don’t go into detail about each step, but mention the subtitles of the steps (I talked about project solutions in my previous resume preparation. The plan should first write a subtitle and then expand into details). Finally, "If you are more interested in which step, we can focus on chatting."
