First applied through a reference and got an email from the recruiter for scheduling a technical interview over the phone. Was given enough days for preparation and a couple of reference videos as well which are there on facebook's career page. The interview lasted for 45 minutes. Was asked only one question. Interviewer introduced themselves and directly jumped on to the problem. Gave me 5-10 minutes in the end to ask questions. Good experience as it was my first interview ever and that too with Facebook. Lacked Practice.

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.
