TikTok Developer interview questions

The interview goes from mid July to end of August which results in a rejection even though I think I performed quite well in the interview. Contacted by a talent recruiter two weeks after I submitted my application. Then it was followed by a technical interview with a medium LC problem. After two weeks, a second interview about two easy coding questions and some computer graphics questions. The last interview was hiring manager with some casual talks about what I've done and computer graphics again. Then after two weeks it resulted in a rejection.

I interviewed with TikTok in August 2020. I applied online and was contacted by the recruiter for the first technical round which was through Zoom and used an online coding platform. I was given LC hard. I didn't get the next round.
