Interviewing with facebook can be a hit or miss. You first get a 45 minute phone screen (1 technical thats usually med-hard difficulty). The onsite is definitely easier, 2 -45 min technical interviews and 1 45 min behavioral. I definitely recommend practicing the medium problems on leetcode, and definitely definitely rehearse what you will say for behavioral, because that matters too.

There were an excessive amount of rounds with a high difficulty of questions for a new grad role. Everyone I spoke too was very friendly though! Study hard and you may be okay.
