Recruiter reached out for an initial phone call with some behavioral and logic questions. She later followed up with an e-mail of several articles to prepare for an interview with the hiring manager.
The hiring manager for the position was unavailable at the last minute so they had someone else on the team conduct the interview. The person that I spoke to was extremely rude and condescending, suggesting that my work at my current employer was not good enough for them, even though I had more work experience than her. After speaking to her, I no longer had any interest in working for Facebook and would not consider applying again.
