After preparing for two months, I frantically brushed the interview questions, 4-sided byte beating, and successfully got the offer

Speaking of ByteDance's experience is quite funny.

At the beginning, I really wanted to go to the game testing department. Of course, I also really wanted to go to the data department, but I could only vote for one in advance, so I voted for the game, but I was hung up the next day. . .

In the middle, the education in Beijing offered me, but I didn’t want to go to Beijing, so I refused. The test in Shanghai offered me, and I also refused. When I was officially approved, I voted for two, the game department and data, but the game was suspended for me the next day. . .

After a few days, the data also hangs up for me! I think it's really against byte fate. . . At this time, senior Ali saw that my performance in the last round of the Ali interview was not very good, and wanted to give me some internal education with Byte, but at this time Data took the initiative to scoop me up! ! ! What a miraculous operation. . .

So much so that I always felt that Byte was prostitution with me, which clearly used me to brush KPI! Can I agree to this? . . . I agreed. . . Facts have proved that it was my villain's heart that judged a gentleman's belly, and I was wrong! orz! At the end of the article, I shared the preparation resource library I prepared for Gold, Three, Silver and Four, including source code notes, Dachang interview questions, job-hopping analysis, resume analysis, project actual combat source code + notes + tools, if you need it, please like it You can get it for free~~

HR face

In fact, it is not an hr interview. It is mainly to understand the situation and then send a letter of intent. The approval process in the middle is relatively long, and I am afraid that I will kneel after waiting for a long time. . . There is nothing to say about the question, basically it is the intended location, which companies and departments you have invested in, what offer you have now, what plan you have, graduation time, where you are from, etc. I sent a letter of intent before the call was over. I felt a little excited, but I couldn't show it. . .

general summary

The original poster is from Hangzhou, but the interview process is still very fast. From the end of the written test on the 16th to the end of the four sides on the 23rd, it takes a total of one week, and then it takes a little more than a week to add the offer approval, and the whole process is completed in half a month. Received letter of intent. It can be seen from the interview experience that Byte does not pay much attention to the project, but more on the mastery and in-depth understanding of the basics, so it is recommended that you review carefully, and do not overestimate the knowledge points

Finally, I hope everyone can get a satisfactory offer! ! !
