That TikTok, a leading player in ByteDance’s global chess game, is now in the same boat as Huawei doesn’t seem surprising. In fact, TikTok’s sale of its U.S. business to Microsoft is not a kneel down, as we imagine, but a forced retreat from an extremely unfavorable situation, so I can understand that.
However, at the same time, I was more surprised and confused. After all, the offer I just got was wasted, and TikTok must not be accepted. I haven’t figured out what decision I should make after that.
I’m from Jiangsu province. I studied computer programming in a university in Nanjing. I have UIUC exchange experience. This year, I got two offers from TikTok and Google. After comprehensive consideration and comparison, I chose Bytedance’s American TikTok Business Division. However, it is not spring, and the impact of the epidemic in the United States is very serious this year, so the entry time has been postponed.
TikTok is now in crisis, and the sale of its US business to Microsoft is almost certain, which means TikTok will definitely not go, but let’s share my interview questions for TikTok, which is byteDance’s business after all.
The following content is shared with my TikTok interview questions and my personal plan for the future. The content is limited, involving the “interview questions answers and analysis” + “resume template”, and the complete PDF version is available for your reference.

Step2. Brush the interview questions of large factories for nearly 3 years
Brush question is to know the domestic line Internet company technology and preferences on the quickest way, the company in general interviewer ask technical problems must be associated with the technology application of company itself, so the brush problem would allow us to have a good understanding in advance to the interviewer will ask what, can accomplish know fairly well, the lines.

- Java Interview guide (Java foundation + algorithm and programming + database + popular framework and new technology, etc.)
Step3. Adjust your attitude and start again
It was a surreal experience, a roller-coaster ride that was hard for anyone to accept. So, adjust their own state of mind is good, it is difficult to let yourself to be a thing, but also has to be one of the things, especially in the study plan and interview, have let oneself hold good state of mind, so during the interview process can play a proper power, not affected by the mood, let sell at a discount greatly.

Likewise, I wish me all the best in the future interview.
