100% remote.

Three interviews total:

• A phone screen
• A 45-minute technical coding interview
• A long final virtual “on site”

The on site consisted of:

• Two 45-minute technical coding interviews
• One system design interview
• One behavioral interview, which also ended in a short coding challenge.

The recruiters and interview coordinators at Facebook are fantastic. They’re always available to answer questions or help you get set up for your remote interviews. They’re enthusiastic and seem to genuinely want you to succeed. The actual interviews themselves were also quite fun, if that’s possible. It felt like a team I wanted to be a part of.
