Applied for Senior EMEA CSM role. The process ran about 2-3 months across four stages: an HR screen, an interview with the hiring manager covering the role and standard CSM questions, a peer interview with general questions on databases and cloud-native infrastructure, and a final challenge. The first three stages were standard and fairly run. The interviewers were professional and the conversations were positive. My main feedback concerns the final challenge. You deliver a presentation to a fictitious customer, with one prep call beforehand, then present to a panel role-playing different customer roles. The exercise is framed as a client meeting, but it functions as a high-stakes role play: candidates have limited prep time and, coming from outside the company, little familiarity with MongoDB's tech. That combination makes it quite different from a real client meeting, where you would have product knowledge and more context. I have no issue with not being selected, that is part of the process. What I found disappointing was the closing feedback: it was generic enough to fit a first-round rejection, and when I asked for something more specific after investing in a multi-month process, my request went unanswered. Overall, a thorough and professional process, but I would encourage more proportionate and transparent feedback for candidates who reach the final stages.
