Facebook has to be the worst company to interview for in the Bay Area when it comes to engineering. Facebook likes to hire engineers almost exclusively from two demographics (White & Asian) and that's it. If you don't belong, then do yourself a favor and do not waste time interviewing with them : Facebook won't hire you. Not only that, engineers conducting the interview will put you under more scrutiny than they would other candidates. You will be at a disadvantage from the first question. Simply, they are not used to hiring engineers from your background and they will set you up to fail the interview, a self fulfilling prophecy. My advice to Facebook is, in general, train well your engineers in regards to unconscious bias and have them certify before allowing them to conduct interviews. In particular, I would add to no let engineers on sponsored visas that have been in the country for only a short time conduct interviews to citizens and permanent (green card) residents as they do not understand yet the race dynamics of the U.S.A. It just does not feel right. It would be fine to let them conduct interviews for other candidates looking for visa sponsorship though.
