Interview byte, HR tiankeng on three sides, I didn't expect that I would capsize in the gutter....

Hades is easy to see, but imps are hard to deal with. I have always believed that there are many good people in this world, but I never thought that I would also capsize in the gutter. I feel like I was cheated by ByteDance's HR.

Here, I just want to warn everyone that the offer must be in your own hands to be true. Verbal offers are not reliable. I hope everyone can learn from me.

Introduction

Last year, Bytedance continued to expand its moves, and there has been news that: Bytedance is recruiting again! You can see internal push codes and recruitment information sent by ByteDance HR everywhere.

Under the swiping screen of the big environment, I looked at the demand for testers in the recruitment information, and there were quite a lot, and affected by the halo of the big factory, I submitted my resume.

However, I did not expect such a thing to happen. As in the title, I feel that I have been cheated by HR.

the whole story

That's right, I went to interview ByteDance, the interview process was very compact, a total of three sides.

The process of the first two interviews went smoothly. I had a pleasant conversation with the interviewer, and I felt that I answered the questions in the interview well. Especially the people on the first and second sides are very nice, and they respect the interviewers during the interview process, they will listen and interact. So far, my interview experience has been fine.

I think the difficulty of the interview questions is medium, and I can basically answer them. Occasionally, there are one or two questions that I don’t know. The interviewer will also give some pointers, and I can follow up. The problem lies on the third side.

Here is a brief analysis of my experience.

tell me about my interview

1. Self-introduction
2. Questions about previous internship experience

12. Rhetorical questions

Three sides

Sanmian is a woman, who should be an HR according to ByteDance's convention, but she didn't introduce herself throughout the process. When I came up, I asked the questions asked by the previous two interviewers again. My attitude was a little cold. I interrupted my answer many times during the interview and kept dissing the interviewer. I was inexplicably nervous.
The specific interview questions are similar to those above, I don’t remember clearly

Advantages and disadvantages of python decorators
redis and mysql Optimal pressure, how to deal with career planning

You can get the specific answer analysis part of the interview questions in the card at the end of the article for free!

She didn't seem to care after I answered these questions, she was basically playing with her mobile phone all the time.

In the end, I directly said "I'm fine, let's do it for today", got up and was ready to leave.

When I asked back, I asked about my interview performance. The HR said that my performance was fine, and the offer was basically available.

Interview result notification

After finishing the three interviews, I felt uneasy. I waited for two days without any news. I asked the HR specialist who sent me the interview email and told me that I passed the interview in the system and asked me to wait. I was quite happy, so I rejected two other good offers, and I didn't continue to interview other companies during the period, but I waited for another two days and still heard nothing.

In order to be able to live a stable life, I asked again on May 1st, and this time told me that the three-sided interviewer did not write an interview review for me, and the hr commissioner didn't know what was going on, so he went to help me verify it.

When I hung up the phone, I knew it was 100% cold.

Sure enough, a phone call came at six o'clock to say that there was no match, but that I highly recognized my ability and other nonsense. In the end, he said that he would help me to see if there were any suitable positions in other positions, and if so, he would contact me again. Basically it's over here.

interview impressions

The overall feeling is that if the three sides are HR, her performance is very disrespectful to the interviewer.

She gives the impression that she always wants to match the interviewer's things. If she doesn't get what she wants, she will say "I don't think you are prepared enough", and the final interview result must be folded on three sides.

The people around me who have interviewed ByteDance are the same as me. The first two chats were very good, and the third one was on HR.

Back to the analysis, I feel that the company does not really need so many positions, it is more like a plan for interviewers to complete the KPI of manpower. In fact, I think it’s best to get together and break up in the interview without delaying each other, but their feedback is slow. First, they give people the illusion of "you are OK", and then hang you, which made me reject the other two. The offer, missed other opportunities.

Later, through the communication in our interview group, we learned that many in-service interviewers failed the interview, but ByteDance called to investigate the in-service unit. I just feel that this is not a decent thing to do. You can't destroy others if you don't want them! How do you let people stay in the working unit?

This HR is a bit tricky.
