Valens Semiconductor interview questions

The two interviewers were nice and friendly. They introduced themselves and their company works, as part of the small talk. Then for an hour and a half, they had some programming questions about the C language. They also wanted to ask questions about threads.

The interview was of a technical nature - at the beginning of the interview I was asked to tell about myself and about a project I did. Next, I had to answer 3 questions in C.
