I applied through an employee referral. The process took 4 weeks. I interviewed at MongoDB in Jan 2023
Interview
I was referred through a friend. Had an initial talk with a recruiter and then supposed to have a technical phone screen which got cancelled cuz of hiring freeze. Then they matched me with another team and I finally had the phone screen which went great. Next step was talking to a hiring manager. The HM had only 3yoe and all of it was at MongoDB. IMO, the chat went great but for some reason they decided to not move forward with me. I still see the position being posted in Linkedin and available in their website. Just waste of my precious time. Won't be interviewing with them again.
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.
