TikTok Research Engineer interview questions

The interviewer totally lacks the ability to articulate his question clearly. He just asked very vague and general questions and didn't know how to provide additional clarification. The interviewer's communication skills are poor.

The interviewer asked me some questions about the projects in the CV. He asked on some deep level and considered the potential of using this technique in their project. After that, I conducted one coding practice, medium level on the Leecode.
