TikTok Intern - Software Engineer interview questions

I had a technical interview with an engineer. We started off with introductions. He asked me 2 Leetcode style coding problems in 45 minutes. Dude was chill. Had some time at the end for questions.

First there is a breif introduction about the team and the company, then the interviewer asked me to do a baisc introduction about myself. And after thet, there is one coding question, which I think should be hard, and it is not a tagged question.
