The interview process consisted of two coding tests, one behavioral interview, and one product design interview, all scheduled back-to-back on the same day. The total duration was about three hours.

In the four weeks leading up to the interview, I was provided with an overwhelming amount of information and study materials.

Ultimately, I did not receive an offer. The reason given was that the way I am assigned work in my current job differs from Facebook's workflow. I wish this had been communicated upfront, as I invested a significant amount of time preparing for the interviews.
