ByteDance interview questions

I did the interview on batch day. However I only made it to 2 rounds technical interview. Not managed to make it to the 3rd round. If I pass, the final round is HR.

Interview schedule changed a few time with different users. One of them even rescheduled 30 minutes before the interview. 15 minutes later, the time changes again after I reconfirmed the new schedule. I’m quite thrown off my the last minute changes and the mood changes instantly from doing any further interviews.
