I had three phone interviews, and I was sure I didn't pass any of them because it took them so long to get back to me.

One round of interview is not easy. It involved using C to implement a producer-consumer loop, as well as questions about operating systems. This was not a LeetCode challenge, so it was hard to prepare.

The interviewers were nice. They asked about memory utility and bitwise questions, and overall were very kind. They elaborated about the role, the company, and the product, so I knew where I was going.
