Hiring process is standard. One phone screen and then onsite interviews.
I have interviewed twice with facebook in last one and half year and both the times, experience has been terrible.
On the phone screen, the interviewer was typing on his keyboard consistently making an annoying sound which makes it almost impossible to concentrate and think. On asking him to kindly stop making the sound, he says "Its my job to take notes while interviewing, I cant help it". I wonder what notes he is taking 2 mins into the interview.
Hiring process is not at all standardized. They can ask any question and all you have to do is come up with flawless code. Doesnt matter what question they ask, come up with the cleanest code of your life or you are doomned(rather saved from being a coding machine). They dont care what your thought process is, or if you type up the solution exactly as given on leetcode, "Code is all we need".
Definitely gives the impression that, they want people who can code like a machine and not ask questions. Well this might be good for people who just want to go to facebook for the sake of name and money(??), but for someone who is interested in a particular field, facebook isnt for you.
Apparently, people who worked as intern there told that the everyone in the company is a coding machine and there is absolutely no work-life balance.
The university recruiter is one of the kind, giving phone interviews to everyone in the university and then rejecting everyone. Either, the whole university is stupid(which is not the case, because people have offers from google, amazon, microsoft etc), or you are just trying to build up numbers. Not a single person from the whole university got offer and almost everyone was interviewed.
In nutshell, Not interviewing again with facebook.
