Couple of base recruiter screeners and then tech screener. This is followed by 4-6 on site interviews , 3/4 of which are technical question based interviews. Lots of questions on Graphs , Nodes as you would expect with Facebook and also things such as depth first or breath first searching.

Got to the stage of a phone screen. Pretty standard phone screen asking about a few data structures and algorithms and solving a leetcode medium question. Its difficult given the time pressure but I managed a solution since I had solved the question beforehand.
