How difficult the interview is! I was forced to survive the six rounds of interview of ant financial! Almost out (interview resumption)

2022-07-27 17:51:00 【InfoQ】

I have developed for more than six years , Ali, who changed jobs from a midstream company P7

, In fact, after these six rounds of interviews, the overall feeling is still good , Before that, I actually had a bad interview with other companies .

The first round ： Team interview

The first round is basically an interview with your team members , Is equal to or higher than you P My senior brother came to meet you , My words basically didn't ask anything special , Mainly about the projects on your resume , You need to be familiar with your project , Personally, I think you should make it clear what your role has done and what you haven't done in the project , Then it's best to focus on the part you do , Then the interviewer will ask you some specific questions from your content , This part varies from person to person , Say what you know and don't say what you don't know . Finally, I will ask you something TCP/UDP ah 、 Basic knowledge such as network model . I think this side, as long as your project is reliable 、 Don't brag 、 Solid foundation , One side should not be a problem .

The second round ： Supervisor interview

This side is actually similar to the first side , It's your senior brothers who have sifted out their resumes , Then I came to your supervisor to interview you, just . On this side, my interviewer still asked me to mainly introduce my resume ( Maybe because I'm a social recruit , They are more interested in project experience ), Then I said it again , Because I thought about it after I finished , So this time, I basically paid attention to the things I didn't mention or didn't speak well last time , Basically speaking, it's ok . Then the next step is to pick the key points according to what you said , There is really no fixed routine in this part , It's what they hear and are interested in. They will ask you if you are “ How to achieve , Why is this achieved , Is there a better way to achieve it ” These three questions , This time, in addition to being familiar with your project , It also requires you to think about what you've done , If you want to , That must be unreliable . This round is at least P8 Level of people , Don't pretend to understand . Or that sentence , know what really understands , Don't know for don't know , It is knowledge. .

The third round ： Cross interview

This side is basically to find another department at the same level as your future supervisor leader Let's meet you again , Prevent cheating in the interview of your own department , The basic routine is similar to two sides , But I will ask you more about your basic knowledge and programming ability , Mainly for the purpose of assessing you , Definitely not to embarrass you , therefore , Come on, just show yourself .

The fourth round ： Code interview

According to my later senior brother, this side was originally two sides , I want to save , But later, due to the process regulations , Added it back to me again , So I went through an online written interview . This side of the interview is to give you an online website , Then you log in with your interviewer , share web page , Then he gives you a question , You come to the scene to write code , Just pseudo code , Then you tell him your logic again ok 了 . There's nothing to say on this side , Write code , It's a mule, it's a horse pulling it out . The problem won't be difficult , My answer is two , Give me half an hour together , The first is to give you a shell command , The function is to read a log file , Then sort according to a field in the log , Then take the top five , Output . Maybe the test point is ：1. You have to read this cat、 Yes awk、 Yes sort Wait, it's quite long at a glance shell command ;2. To achieve it ;3. Spatiotemporal complexity / efficiency ;4. clear . The second topic is inverting strings , It's probably a string “123456789” Separate from the middle , Then reverse them separately , Then the output , The output is “432159876”. Maybe the test point is ：1. To achieve it ;2. Spatiotemporal complexity / efficiency ;3. clear ;4. Try to give an optimization scheme ; It's probably this type of question , It won't be repeated , Elder martial brother said that it was probably the problem they encountered recently when writing code , I'll ask you directly , So there is no fixed routine , You don't have to cram for questions , It's good to go along with fate .

The fifth round ：boss interview

When you get to this side, it's basically stable , Of course, I've seen hanging . This side is your supervisor. Your supervisor is here to meet you , I still talked about the project first , Then pick the point and ask , However, the obvious difference from two or three sides is that he will ask you for higher-level solutions , Don't stick to what you do , It will let you explain the solution of your project and your own thinking as a whole or in part as a whole ( The above three questions ), It will let you try to give a better solution , And explain why . I personally feel that this side is more to test your overall view , If you stick to your little world , That'll probably suffer . Of course , The interview is divided into people , Some non-technical supervisors just chat with you about their life ideals , If you don't match It will be eliminated .

Sixth round ：HRG interview

Talk about life, talk about ideals, talk about three outlooks, talk about salary , As long as you are not anti human, no nonsense , Just ok.
