After attending a conference and talking with several people from Facebook who were also present, I was contacted via email to see if I was interested in an interview.

I accepted, and my first phone interview took place a few days later. During this interview, I was required to complete a recursion assignment and create a polyfill in a shared code environment. While the recursion went okay, I was not satisfied with my performance on the polyfill. This portion of the interview lasted approximately 40 minutes.

I was surprisingly invited for a second phone interview, which also included a recursion question. Unfortunately, I made the problem more challenging than necessary for myself.

Following this, I was invited to Facebook HQ for four in-person interviews. These interviews covered topics such as recursion, closures, CSS, and implementations. Regrettably, I was not deemed a good enough fit for Facebook, which affected me for about a month. Although I believed I performed well, I took too long to get started on the tasks.

The recruiters and interviewers were excellent. The entire process was smooth and comfortable.

Questions about recursion, CSS positioning, what you would like to do at Facebook, and closures.
