Preface
Whether it is school recruitment or social recruitment, various interviews cannot be avoided. The written test, how to prepare for these things is particularly important. Whether it’s a written test or an interview, there are rules to follow. What I mean by “rules to follow” just means that you can prepare in advance for technical interviews.
After strategizing, the decisive victory is thousands of miles away! Without fighting an unprepared battle, I think everyone can prepare for the interview first from the following aspects:
- 1. Introduce yourself. (You can definitely introduce it like this: "My name is XX, gender, where I come from, which school is, what I love to do", remember: talk more about what is not on your resume_, talk more about where you are better than others!)
- 2. What knowledge points may be involved in the interview and which knowledge points are the key points.
- 3. Which questions will be frequently asked during the interview and how should I answer them during the interview. (It is strongly not recommended to recite questions, first: how much can you remember by recitation this way? How long can you remember? Second: the study of recitation methods is difficult to persist!)
- 4. How to write your own resume.
"80% of offers are in the hands of 20% of people" is not unreasonable. Although strength occupies a large part of the factors that determine your success in the interview, if you have bad mentality or bad luck, you still cannot get a satisfactory offer. Aside from luck, let’s take the mentality as an example. Don’t be discouraged or doubt your abilities because of the interview failure. After the interview fails, sum up the reasons for the failure. Later you will find that you will become stronger and stronger.
In addition, the important points for everyone to be clear are:
- 1. You must be cautious about what you write on your resume. This may be a place where the interviewer asks a lot of questions;
- 2. Most fresh graduates have no work experience or internship experience when they find a job;
- 3. It is very important to show your project experience perfectly.

Write at the end
- 1. Be cautious about what you write on your resume, and you must be very familiar with the things on your resume. Because under normal circumstances, the interviewer will ask based on your resume; 2. It is also very important to have a project that can be on the table. This is likely to be a place where the interviewer will ask a lot of questions, so review it before the interview Take a look at the projects you have done;
- 2. Talk to the interviewer about basic knowledge such as the use of design patterns, the use of multi-threading, etc., which can be combined with specific project scenarios or how you use them in daily life;
- 3. Pay attention to your own open source Github project, the interviewer may dig into your Github project to ask questions;
- 4. It is recommended to know in advance the values of the company you want to interview, and judge whether you are suitable for the company.
In addition, I personally feel that the interview is also like a brand new journey. Failure and victory are common things. Therefore, I advise you not to become discouraged and lose your fighting spirit because of the failure of the interview. Don't be complacent because you passed the interview. What awaits you is a better future. Keep up!
