    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.

    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.
