TikTok Software Developer interview questions

The first round is online assessment which has two questions about the theory, one SQL, two algorithms. The two algorithms I did were all about stirng manipulation. I think the emphasis is on the code implementation rather than the logic.

Bad experience from interviewer, who asked personal question with no relation to the position. Unprofessional interview for absence midway to go for toilet. But HRs are in high efficiency and professional working manners.
