TikTok Software Engineer-AR Effect Platform Position interview questions

A 15 minutes Zoom call. Then follow by multiple rounds of technical interviews. Only get to the first round. The technical interview takes about an hour with 1-2 coding questions.

I had to make a 3 days project that took me over 24h of work in the first stage. After that, I got to a phone interview that was done by 2 Chinese people where one of them did not speak English and would talk to each other all interviews. They kept asking about Graphics programming when I never stated on any point that I knew about it. After that, I had a coding question that was not hard but the interviewer had no interest in continuing my interview and kept asking me if he could just finish the interview.
