TikTok Software Developer interview questions

First step was online assessment with 4 questions. Second step was a techinal interview, asking a leet code medium level question, previous experience, knowledge about system design, and computer science

No offense and hate, I am just describing the interviewing experience. I feel that it is quite hard to understand the accent of the interviewer when it comes to technical terms. So, I believe this could be the challenge in throughout the interview.
