I applied through university. The process took 4 weeks. I interviewed at MongoDB (Pittsburgh, PA) in Oct 2017
Interview
1 recruiter screen (about experience/what do you know of mongodb), followed by 1 coding interview over the phone (with a women which I liked, because I am a women in tech), and then virtual on-site with 3 interviews (all coding). Really nice interviewers - they seemed excited about working at MongoDB, and answered all questions with patience!
Interview questions [1]
Question 1
Signed NDA, but questions were pretty standard, and the interviewer was happy to help you out when/if you were stuck.
First had a phone call with a recruiter, then a technical assessment through a third party (with a person, not one of those websites), and then a three hour interview with three members of the team. Two of the three hour segments were coding, and the other was a behavioral.
