ByteDance Developer interview questions

I got a link to take the assessment after applying through LinkedIn. I applied for software engineer role. I have 2 hours to solve 3 problem with easy, medium and difficult problems. The easy one is like pattern matching while the hardest problem is dynamic programming problem.

The interviewers were very kind and the procedure was high-efficient and professional. The first round is on the phone with your potential manager. The second round is in-person. There was 1 week between the first and second round.
