What preparations do you need to make for the interview ？

Next, we will divide ： Before the interview 、 During the interview 、 After the interview   Three parts , Answer some common questions .

Before the interview

How to find an interview ？

• push ： First of all, I recommend you to take the internal push approach , The pass rate of internally pushed resume is much higher than that of other methods ; The ways to push inward are ： Contact the working elder martial brothers and sisters 、 Find the corresponding internal tweet on the Forum 、 Attend the school recruitment publicity meeting   etc.

• Direct delivery to the recruitment official website of the corresponding company ： We need to know which companies we want to invest in , Directly search the company's official recruitment website （ Big companies generally have ）, Find the position you want to post

• Relevant recruitment website delivery ： On various recruitment websites HR The corresponding recruitment information will also be published , It can be delivered accordingly

What needs to be done for the interview ？

• A good resume
  ： Be able to explain   School 、 Education 、 internship 、 Technical project experience in school   etc. , Specifically in the sister chapter 《 School recruitment —— Technical resume guide from the interviewer 》, Coming soon .

• Understand the post requirements of delivery
  ： That's what we often say JD（Job Description）, The company's official recruitment website or published recruitment information will describe in detail , If you can't find it or the company doesn't write , Can contact HR Email instructions .

• Review the relevant knowledge of the interview position
  ： School recruit students need to review   Fundamentals of computer （ The Internet 、 operating system 、 The principle of computer organization 、 Mathematics, etc ）、 Coding ability （ data structure 、 Algorithm ） 、 Basic knowledge of technical direction （ For example, front-end students mainly look at html/css/js）

• Organize your own projects
  ： Including internship programs 、 Personal projects 、 Scientific research and academic projects 、 Participate in community open source projects, etc , You need to introduce yourself during the interview , The interviewer may also ask about the content of the project according to your resume .

• Do some algorithm problems properly
  ： front end 、 Some positions such as testing may not pay special attention to Algorithms , But doing some algorithm problems can train your thinking 、 codability ; Common question brushing websites ：LeetCoode、 Cattle from 、 Universities OJ etc.

During the interview

How to introduce yourself ？

When introducing yourself in a technical interview, please focus In the direction of Technology , Some students will prepare a gorgeous opening speech , Introduce your student union during college 、 Experience in organizing activities , These contents are not very attractive for technical interviews , It's not good for the interviewer to find the right question for you , Sometimes it will reduce the score in the eyes of the interviewer （ I don't feel focused enough on Technology ）.  Suggestion is ：

• Students with technical internship experience , Focus on the projects done in the internship , Explain your role in the project 、 Responsible for developing those parts 、 What technology stack is used 、 What have you learned .

• Students who have no internship experience , You can introduce what you have learned in the technical direction of the target position 、 Have you done any personal projects   Or some Demo project .

• Yes
  ACM Such as computer competition winning experience
  It is necessary to explain , pluses .

• Yes
  Participate in open source projects or community building
  Of , Suggestion description , pluses .

• Academic Daniel students can also explain that they have published papers 、 Participation in the meeting , Plus points, too . If the academic direction has little to do with the work content , It is recommended not to go into endless details , If the academic direction is just the same as the post match  or   The interviewer is interested in , Interviewers usually take the initiative to continue talking .

No internship experience is OK ？

The answer is —— Tolerable .  It's good to have technical internship experience , But for school recruitment / For interns , Not everyone has internship experience , Or the internship experience may be different from the current position match. So don't worry too much about , Generally, students who can participate in the interview through their resume , They have been preliminarily recognized . Students without relevant internship experience , During the interview, you can highlight your advantages in other aspects （ Such as ： Personal projects 、 Open source project 、 competition 、 academic , Refer to the last question ）, If the interviewer recognizes your knowledge reserve 、 Ability 、 The potential will pass .

No,   Related internship experience   and   No relevant knowledge and ability   Two different things. , Students who have internship experience and lack the ability to accumulate knowledge , The final evaluation may not be as good as   Explore students with relevant knowledge through their own learning . So please be sure to prepare for the interview , Make yourself meet the requirements of the interview position , For example, students in the front-end post , At least learn html/css/js Related basic knowledge , Have a certain understanding of the current common front-end technology stack , And have hands-on experience .

Do you need to know the business ？

The school recruit / Internship   Come on , Don't force an understanding of the business , Generally speaking, it is difficult for school students to have an in-depth understanding of business , Having relevant experience and understanding is, of course, an extra point .

The whole interview process

Generally speaking , A complete interview includes ： written examination 、 Technical interview 、 Position match、HR interview .

written examination

： Maybe it's an online written exam   or   Written examination on the spot , The scope of the written examination of school recruitment is wide , Will involve basic computer knowledge 、 Knowledge and skills in the interview direction 、 Code coding、 data structure  &  Algorithm   etc. .

Technical interview

： Take byte jitter for example , School enrollment is usually 2-3 Round cross technical interview , Internships are generally 1-2 round , Investigate   Fundamentals of computer 、 Coding ability  、 Technical direction, basic knowledge and technical depth 、 System design capability 、 Abstract ability and engineering ability 、 Soft quality   etc. . On the one hand, it is more inclined to basic knowledge 、 Technical breadth , Two or three sides are inclined to technical depth 、 Advanced ability .

Position match

： Usually after passing the technical interview , Interview by the head of the business department , Prefer soft quality 、 Professional ability 、 Personal development and planning, etc .

HR interview

： It's usually the last interview , Mainly talk about career planning 、 Personal appeal 、 Some questions during the interview 、 Entry related information （ If available, the entry time 、 Internship time 、 Working place, etc ）

How to deal with problems that won't happen ？

First of all, make it clear —— Everyone will have no problem . Even social recruitment students who have worked for many years will have a knowledge blind spot , Some questions won't affect your overall interview evaluation . therefore ,

Don't pretend to understand

, This will leave a negative impression .  If you really won't, please explain directly to the interviewer , You can ask the interviewer to give some tips , Or consult the interviewer to see if you can access relevant materials on site （ Be sure to check with the permission of the interviewer , Otherwise, it is easy to be counted as cheating ）. If after prompt or inquiry , Solved problems that would not have been solved , Plus points, too —— Explain learning ability 、 Resilience 、 Pressure resistance can

  Good strength .

What questions can you ask the interviewer during the interview ？

After a round of interviews , The interviewer may say ：“ Do you have any questions to ask ？” ——  Be careful , This may also be an interview question , The interviewer wants to pass your question , Understand your career aspirations 、 Personal planning 、 Learning ability, etc , So choose your own problems carefully .  During the technical interview, it is not recommended to ask questions that have nothing to do with the current interview 、 Involving company secrets 、 Personal privacy issues , Such as ： How much overtime / Wage treatment （ This is in HR During the interview, you can ask ）、 Current earnings of the company 、 Core technologies specifically used by the business line 、 Interviewer contact information, etc   You can ask some technical questions related to yourself , Such as ： If you pass the interview, what do you need to learn to prepare 、 The interviewer's comments and suggestions on your current round （ If the interviewer is inconvenient to say , And don't ask ）、 The solution to a confused problem during the interview （ Time limits the interviewer may only be able to give ideas ） etc. .

After the interview

How to deal with a long time without a response ？

Please check your email after the interview 、 Keep the phone open , If for a long time （3-5 God ） No response , Recommendations and HR contact . Students recruited by the school are usually afraid and HR communication , Worry about yourself “ Schrodinger's cat ” The result of the state is in their own connection HR Then it becomes negative , This mentality must be overcome , Timely confirmation of the interview results is conducive to the arrangement of subsequent interviews /offer choice .  If you really get bad results , You can also try to ask HR Questions in interview evaluation , You may not get an answer , But if HR Being able to tell you also helps you find out in time 、 Solve your own shortcomings , Lay the foundation for the next interview .

If you fail in the interview, can you deliver it again ？

Some companies have a mechanism that does not lock resumes during interviews （ Delivery is invalid for a period of time ）, This can also be compared with HR make clear by asking sb. .  Our company （ Bytes to beat ） I don't lock my resume , If you fail to pass a job interview, you can continue to deliver . But I suggest you prepare carefully every time you deliver , Every time you deliver 、 Interviews can be recorded , If you have multiple interviews 、 Delivery does not reflect growth , It will also affect the subsequent resume screening and interview .

Can you share the interview questions after the interview ？

You can record interview related questions by yourself 、 Experience , Prepare materials for your future interview , But it is not recommended to share immediately （ Including sharing on the Internet and sharing with other students ）, Some companies take written exams 、 An agreement will be signed during the interview , If you find yourself sharing the latest interview 、 Written test questions , You may be disqualified directly .
