    Positive Experience
    Easy Interview

    Application

    I applied online. The process took 1 day. I interviewed at Qualcomm in January 2017.

    Interview

    Applied for Software Engineering Internship as a Sophomore/Freshman. Was contacted about interviewing about the EIP and schedule two, back to back, phone interviews. One was behavioral and one was technical.

    The behavioral interview asked general stuff about my background, why I chose to major in CS, and what I knew about Qualcomm. This was extremely pleasant and went very well.

    The technical interview, after a few breaking-the-ice questions regarding my background and whatnot, consisted of three questions. The questions where fairly straight forward - I went over basically these exact questions during my CS courses - and I answered them fairly easily. I answered the questions with Java.

    However, a week or so later I received a call from my behavioral interviewer saying that they were unable to offer me a position and that I should apply again next year.

    Negative Experience
    Difficult Interview

    Application

    I applied online. The process took a week. I interviewed at Qualcomm (San Diego, CA) in January 2017.

    Interview

    Applied online, got an invitation for a phone interview. Recruiter told me it would have C++ quiz that would last 30 minutes. Had the phone interview with him, after 5 minutes of going through my resume he began the C++ quiz. 90% of the quiz was on pointers. It took him 30 minutes to figure out how to screen share and it was very difficult to understand him because of his thick accent. He was also very rude when I asked him to repeat the question because I could not understand him.
