I was approached by a Facebook in-house recruiter, but I wasn't interested at the time. I contacted her back a year later. After a couple of emails, we had an introductory call.

That was followed by two phone screens:

• One around coding, on Coderpad.
• One around Linux systems and troubleshooting.

The recruiter was pleasant and responsive. She even got in touch a few days after the phone screen to apologize for not having feedback yet.

The coding interviewer was not great; he offered very little in terms of interaction or clues. I coded the first problem, and he didn't question anything, yet asked me to go over it line-by-line logically. I'm not sure he understood what I was trying to do. As we were short on time, he moved onto the second question, but with too little time remaining. Overall, it was not a great experience.

The troubleshooting interviewer was much better. We had meaningful interactions and were able to discuss the problems he presented.

One of the coding questions was to generate a minesweeper grid (2x3) with 3 randomly-placed mines.
