Straightforward and efficient process that took about 4 weeks. The recruiter was always around for any questions I had and informed me quickly (either the day of or the following) of what next steps would be.
- Walk me through your resume

The interview process included a call with the recruiter, a video call with the hiring manager, and a portfolio presentation with the team. Overall, I had a great experience - the recruiter was personable and responsive and the whole process was clear and organized.
- - Why UX research? - What is your research process? - How do you collaborate with designers, engineers, etc.? - If you are moderating an interview and find out the participant doesn't qualify, what do you do?

The recruiter was very responsive and had excellent communication. The process was very pleasant and everyone I met with was professional and transparent. Overall a very good experience and I was grateful to have the opportunity to meet with so many knowledgeable team members.

Anonymous Interview Candidate in San Francisco, CA
I applied through college or university. I interviewed at MongoDB (San Francisco, CA) in Sep 2023
During interviews conducted in my preferred programming language, I encountered interviewers displaying bias. Despite correctly solving questions using optimized approaches well ahead of schedule, they seemed reluctant to ask further questions or explore my skills thoroughly even though it was a great match to what they were expecting
- word dictionary, from set of words
Hi all, I just had a tentative offer for a CSM role at MongoDB. Last stage is in a week. It seemed like the package was non negotiable during the tentative offer call and she asked me if I would accept as is. What do you think are my chances to negotiate it if I were successful?
Always try - but go into negotiations confidently, stating that you received another offer from another firm etc and you’d like to see if MongoDB can match it. See what they say! Worst they’ll say is no, but at least you can sleep easily knowing you tried. it’s tricky if you already tentatively said the salary recruiter’s offer was ok so if you DO counter (as all candidates do), this time you may not want to go too far from the stated range. They likely have a salary band they’re staying within

Very friendly hiring manager. Was looking for a Senior CSM with more experience in account management skills and with a good technical background. The interview started as a casual conversation leading to Tell Me about yourself, exchanging details about the role, and tying it back to skillset.
- Tell me about yourself and skills
- Your current role as a CSM
- Account and relationship management skills

I applied online. The process took 3 months. I interviewed at MongoDB
Interview process took 3 months. Was strung along 9 rounds, with never ending rounds of interviews with no end in sight for final decision. Most interviews (6 rounds) were after interviews with hiring manager and head of group, which went positively, and there was a break in communication for 3-4 weeks before recruiter reached back out. No replies to my follow-ups in the meantime. No facilitation of process despite pending offer from another company, and many, many interview rounds with no end in sight. Recruiters didn’t answer my emails when I asked for areas of focus and purposes of later interview rounds, and those later rounds asked same repetitive questions as earlier rounds. Recruiting coordinator also needed to be prodded several times to reschedule an interview, all the way up to 1 day before original scheduled date.
- Standard behavioral questions, and examples of cross-functional collaboration and analytical projects

Anonymous Interview Candidate in Dayton, OH
I interviewed at MongoDB (Dayton, OH)
Very complicated and tedious. I went through a minimum of 12 rounds with various tasks, tests, builds, presentations and met at least 8 people. I was also told I was over qualifies, under qualifies and handed to multiple hiring manager who did not know what was going on. After 12 rounds and nearly 2.5 months, I was told I did not get the job because I was very under qualified.

I applied through a recruiter. I interviewed at MongoDB
Recruiter call- typical recruiter call. First Interview with hiring manager- recruiter sent a ton of prep suggestions, which I appreciated, but it ended up being completely unnecessary. The conversation was extremely informal and they hardly asked any typical interview questions. Assessment- supposedly a lot of weight is put on this. There are some very easy math and verbal reasoning questions. The rest was like a weird personality test. For a company that is supposedly committed to DEI, I was a bit put off by having to identify as male or female before starting the test. I guess non-binary people need not apply. Second Interview- hiring manager and skip level. This was where it became odd. Instead of inviting me to the office, they suggested drinks after work. Since one of the two people was late, the first 15-20 minutes was basically like an awkward first date, with questions about where I’m from, how long I’ve lived in the area, etc. When the second guy arrived, they spent 10 minutes talking among themselves about non-work things. There were maybe 3 questions during the entire “interview” about my qualifications, two of which were interrupted by the waitress. The rest was just random chit chat. After two days I got an email saying the position was filled, which I knew wasn’t true because I happened to know other people they were interviewing (who were invited to lunch instead of drinks). Overall, I was left very confused as to what they were basing the decision on. Seemed like they were looking for a new friend vs an employee.
- Where are you from? What do you like to do on weekends? Where do you live? What companies have you sold to recently?

Phone call with recruiter, meeting with 1 manager, then half-day of interviews where you meet with a few colleagues and potential managers to discuss your one-pager than you created. Also discussed different aspects of product marketing and how I would market certain technical products differently
- Asked to create a one-pager about a product

I’ve heard pretty positive things about them overall. I think they’ve had some restructuring recently as they’ve been growing but the people I’ve talked to are happy there regardless of growing pains. WLB gets difficult to maintain at times but it’s not a constant struggle.
