TikTok Software Engineer interview questions

after OA, there is 1 tech screening + 1 hiring manager tech screening + 1 skip manager behavioral. questions ranging from leetcode medium to hard including backtracking and dynamic programming. hr verbal offer -> hr official offer letter

There was a pre-screening interview, after which they were going to have some rounds of technical HackerRank interviews. I didn't make it past the pre-screening interview. It was the standard "Explain X in your resume", kind of questions, but the role I had applied for was just not something I had any experience in.
