    Average Interview

    Application

    I applied through a recruiter. I interviewed at MongoDB.

    Interview

    Basic phone screen with recruiter - basic behavioral questions.
    Then, they set you up for a technical phone interview. Mine asked some basic questions about what databases are and then we moved onto the technical problem.
    I made it to the final round, which is a three hour video interview with 2 technical problems. The first one was very easy and the second was medium leetcode difficult.

    Interview Questions

    • Prepare for the behavioral interview if you make it to the final round. I believe that's what held me back.   Answer Question

    Neutral Experience
    Average Interview

    Application

    The process took 4+ weeks. I interviewed at MongoDB (New York, NY) in January 2018.

    Interview

    Applied online and got an email about an HR call. Call was pretty typical, make sure you know why you want to work at MongoDB and what they do. After this received an invitation to a technical phone interview over a coding platform, pretty easy question. After this was invited to interview in person at the HQ. The inside was paid lunch with new grad employees and then 3 back to back interviews, 1 with a hiring manager and 2 with engineers. Overall fairly standard process.

    Interview

    30 min phone screening followed by a 45 min technical interview scheduled a few weeks later. Asked 3 technical questions that built on top of each other. The interviewer was not helpful when asking for clarification questions and even dropped the call half way through when interrupted. Very unprofessional interview.

    Summer Interview

    Positive Experience
    Easy Interview

    Application

    I applied online. I interviewed at MongoDB.

    Interview

    I applied online, a recruiter contacted me for an initial phone interview. We just went through my resume for about 15 minutes and then we talked for about 30 minutes about any questions I had about the internship program. Then I had a 45 minute technical interview. There seemed to be some organization issues on their end, as initially they told the interviewer 2pm when it was actually at 3pm, and they had scheduled two different interviewers for me and they both tried to call me, but they sorted it out. Asked some basic data structures questions on the difference between Linked Lists and Arrays.

    Senior Software Engineer Interview

    Anonymous Interview Candidate in New York, NY

    Negative Experience
    Easy Interview

    Application

    I applied through a recruiter. The process took 4+ months. I interviewed at MongoDB (New York, NY) in November 2017.

    Interview

    I was contacted by a recruiter on LinkedIn and showed interest in me for a job position. In my process, I had 2 phone interviews (director and hiring manager). Since I did not have time to come for an on-site interview, recruiter arranged 2 video interviews. I did well in all interviews and in my last video interview, I asked the director about next steps. He mentioned that if I came up to this point, it means I am about to get an offer after this. Next day recruiter calls me and talked about numbers and RSUs. I did not agree with some of the numbers, he went back and changed the numbers. Everything was going good and I was expecting an offer letter. One day recruiter calls me and asks me to come on-site to meet the team before he can extend me an offer. I came on-site and had a 3-hour interview with the team. Everything was good and the recruiter told me that he will let me know with a day or two. Nothing happened for a couple of days, I called the recruiter and found that had other candidates to take interview before making a decision. After a month they told me that they have selected another candidate, which is more suitable for the job. I am not happy the way they moved forward. My interview process from start to final decision took 4 months. Also, I did not understand why they were talking about Salary and RSUs. I was pretty shocked at how unprofessional the process was.
    I am very disappointed with company work culture and ethics. I won't recommend anyone to MongoDB. The interview process took 4 months and it was a waste.
