    Positive Experience
    Difficult Interview

    Application

    I applied through a recruiter. The process took 2 weeksinterviewed at MongoDB (New York, NY) in May 2013.

    Interview

    Was contacted by recruiter who had found me on LinkedIn. Phone screening, then invited for on-site interview. Six interviews in a row on a single day. I was impressed by the high standard they were looking for, this was way beyond what I expected from a small startup. They made it clear I was exactly who they were looking for, and wouldn't let me leave the building without making an offer.

    Interview Questions

    • Complex exercise in system design, where each reasonable answer unlocked a further level of complexity. Exciting discussion.   Answer Question

    Positive Experience
    Average Interview

    Application

    I applied online. The process took 4+ weeksinterviewed at MongoDB (Palo Alto, CA) in March 2015.

    Interview

    2 phone interviews followed by 3.5 hour long series of Skype and in person interviews (4 in all).

    The process was quite pleasant and the office had a very informal feel to it.

    And of course, you should be prepared to work 50-60 hours a week which includes travel time (flying out of town 50-60 % of the time).

    Overall, they have a a very good team and I think it would be an enjoyable place to work at.

    Interview Questions

    • Data Modeling (University, Course and students problem), SQL, Simple implementation of Linked List, Multi Phase Transaction implementation using a State Transition Diagram, DB concepts like ACID, System Architecture problem involving millions of users and tracking their activity and finally, troubleshooting a slow DB.   1 Answer

    Interview

    Phone Interview: after email from recruiter. The recruiter I think was hiring not only for this company but others too. Anyway, after this, she decided not continue with the process even though my interview was perfect. It was not technical, Behavioural stuff: about my projects, etc

    The process took 1 dayinterviewed at MongoDB.

    Interview

    Their recruiter reached out to me on LinkedIn. He gave me great info about the job and explained how the consulting team fits into the company. He ended up scheduling a second round with the Director. They ended up passing on me but the recruiter was professional and even took the time to call and explain why they decided to pass when I emailed him...which I did not expect.

    Average Interview

    Application

    I applied through an employee referral – interviewed at MongoDB.

    Interview

    Was referred by a friend, but took over a month to be contacted by an internal recruiter. Internal recruiter did not have a great bedside manner, and was difficult to work with. I gave him my availability for an onsite and then he never responded to me - I just got an email to confirm my interview from a coordinator 12 hrs beforehand. Experience with recruiter really turned me off to them. Also, the job description changed 3 times throughout my process with them - they had no idea what they wanted!

    Interview Questions

    • I was asked very straight forward questions about how I would go about solving a specific problem (eg: how would I approach audience segmentation and communications for email marketing).   Answer Question

    Interview

    Behavioral and technical phone screen. Followed by 3 back to back onsite interviews. First onsite is more behavioral, second and third are technical. The interviewers are very friendly and the questions are not too difficult, but stay calm and talk through your thought process.
