I was contacted by a Facebook recruiter. The entire process was efficient and quick.

After the initial phone call with the recruiter, I received an email with details about the interview process and how to prepare for the technical interview in general, which I thought was pretty nice.

I was scheduled for the phone interview one week later. The phone interview included behavioral questions and an online coding challenge, and it took about 45 minutes.

It started with typical introductions, and then I was asked to talk about one of the works/projects listed on my resume and why I would pick to talk about that particular one. The interviewer didn't seem impressed by the project I picked to discuss.

There were a couple of behavioral questions (e.g., conflict resolution, etc.).

The longest part of the phone interview was a coding question. You could pick any language you liked, which was a plus.

The coding question was not difficult, but clearly not an easy one; it required some thought. Be prepared to provide test cases. I had it working but not covering many edge cases.

At the end, you could ask the interviewer any questions, which I did. It sounded like the interviewer wasn't excited about the current work, but was kind enough to give me details about the challenging parts and current interesting problems the interviewer had been working on.

I heard back about the interview result from the recruiter exactly one week later.
