I was approached by a Facebook recruiter via LinkedIn. Phone interview with recruiter to see if I was a fit. Then a half day on-site interview at Facebook HQ. Recruiter prepped me very well for the interview which was in two parts. Firstly a 45 minute portfolio review with a product designer showcasing two projects. Then some questions. Then immediately another 45 minute interview with another designer to do an app critique (Spotify). I was then told I would hear back within 48 hours. 2 weeks later I got a generic email saying they were no longer pursuing my application and they couldn't offer any feedback which was very disappointing.
