TikTok Software Developer interview questions

Had a screening interview with HR and then one with the hiring manager. Positive process with good feedback as to why I wasn’t suitable for role which was helpful to know

Had phone calls with recruiter first . Then I had 3 rounds interviews separately, came one by one. Only when you pass one, you can schedule another one. The first one is coding, 2 questions. The second one is system design. The third is mix.
