TikTok Machine Learning Engineer interview questions

The first step is an OA with 4 questions. The first three are classic leetcode style questions, the last one is a question that was probably created for the assignment. It seems like the examples given and the test cases do not follow the guidelines though.

A coding question and some ML theory questions, and then followed by some Q/A about the company. Overall it’s not very hard, but I didn’t get passed to the next round.
