I applied online. The process took 2 months. I interviewed at MongoDB (New York, NY) in Nov 2022
Interview
Applied on the website and received a recruiter call in a week. The interview totally has 6 rounds, first is a phone interview(technical), then if the phone interview goes well, there will be an onsite interview broken into 2 + 3 rounds. For every interview, I got response in 1-2 days, which is pretty effective and the recruiter were willing to have a call with me before and after each major milestone to let me know what to expect next. Overall the interview process is very impressive and everyone is friendly.
Interview questions [1]
Question 1
Typical computer science questions including data structure/algorithms, concurrency and some design questions. Usually interviewers like to discuss about your experience at the beginning, especially if you have database background.
Interviewer had a particular solution in mind that took a different approach from my own. My solution was algorithmically correct but not one that they were familiar with and preferred a non-closed form solution.
