TikTok Software Engineer I interview questions

I had an interview with Tiktok last month. The whole process went smoothly. The interviewer and I had a nice conversation. I also completed the coding question. I thought I would move to next round. However, they didn't move me and didn't give any response.

4 coding questions in 2 hours that I had to compete on a specific day between certain hours. The questions were leetcode medium-hard, but TikTok centered so they were phrased as if I was working on a real problem there.
