I applied online. The process took 6 weeks. I interviewed at MongoDB in Oct 2021
Interview
Typical process - recruiter call, phone screen, virtual on-site. Their tooling was intuitive for following the interview journey - complete with headshots of your actual interviewers coupled with zoom and coderpad-like links (I forget the actual platform used).
Interviewers were passionate about their work and happy.
Overall I will say that the interviews were harder than many other places but fair, and allowed me to display knowledge. No "gotchas". Interviewers were interactive and receptive to questions.

Interview
The interview process was well organized and flowed smoothly. However, it had quite a few stages, starting with an HR interview to assess my background and skills, followed by a technical interview that included a live coding exercise and several in-depth technical questions. Overall, it was a thorough process that effectively evaluated both technical ability and problem-solving skills.
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.
