1. Phone Interview: A general phone screen. Less than 15-30mins. 2. Followed up by a face to face interview with 4 different persons from different roles, scheduled back to back, with a break in between. This process might take 3-4 hours so be prepared to spend possibly half a day interviewing. 3. Did not manage to proceed to the next round which is supposedly a video conference call with Facebook HQ and then maybe another final round of interview before confirmation.
