TikTok Software Developer interview questions

The first appointment was canceled 30 minutes before the interview. It was rescheduled to one week later. The first round is a technical interview that includes a Leetcode exercise, with the problem focusing on implementing a calculator.

Recruiter reached out to me and I had the recruiter call and then the first technical interview next. I didn't pass this interview, but the next steps were the final interviews 4 rounds
