I applied through an employee referral. The process took 6 weeks. I interviewed at MongoDB (New York, NY) in Nov 2018
Interview
One phone screen, one technical phone interview and three interviews at an on-site. There was also a meet-and-greet with recent grads. Really nice people and not all white, male engineers.
Interview questions [1]
Question 1
Tougher conceptual and design questions in problems requiring standard algorithmic knowledge. Typically harder problems with very engaged interviewers. They really worked with me to solve all of the problems, and they were helpful when I got a little stuck. Very competent engineers. They were clearly looking for behavioral qualities/problem solving strategy alongside fundamental CS skills.
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.
