TikTok Developer interview questions

Very bad interview experience. The interviewer didn't pay attention to me and worked on his own things during the interview, refused to talk to me in some degree and seemed to want to end the interview quickly so he could worked on his things. I am glad that I got rejected, otherwise I may need to work with this kind of people.

Very bad communications. After I passed the initial round, I was moved onto another round of interview. When I passed the second round of interview to move to "final round of interview", they did not respond for a month. When I sent couple emails to check on status as I had other interviews that I needed to finish and schedule along, I received no response. After about a month, they just informed me that I passed the last round but was put on hold due to their hiring and acquisition-related issues. After about another month after, I did 3rd round of interview with a hiring manager, I believe. The manager specifically told me to just stop explaining my thought process and algorithm and just write your code. I did well for the coding part but could not answer some of the questions he asked well. I got a feedback that they would like to interview one more time. I couldn't solve the problem given. I think it was one of the toughest problems. After such a long interview process, I just received an email telling me that I got rejected without any additional feedback. Afterwards, I received couple other recruiter emails from Tiktok and, then, was informed that they saw my previous history of interview and would not move forward when I scheduled the calls. In general, I could see that the culture is probably really bad at the company.
