    DSP Software Engineer Interview

    Positive Experience
    Average Interview

    Application

    I applied through college or university. I interviewed at Qualcomm (San Diego, CA) in March 2017.

    Interview

    Applied through the university career fair. Got a call for phone interview two weeks after I applied.
    Phone interview was 50 minutes long with basic questions about embedded systems and real-time concepts. A couple of days of brush up should see you through this.
    On-site interview had 6 rounds including a lunch interview. Lots of questions on realtime time concepts were asked. Make sure you understand the complete memory layout. Assembly and pseudo codes​ were asked. Questions related to projects (I did) closely aligned with their work were drilled on.

    Interview Questions

    • Couple of questions on my major (DSP/com) were asked, and I was sort of caught off guard. This I believe had a major impact on the result.   Answer Question

    Data Scientist Interview

    Easy Interview

    Application

    I applied online. I interviewed at Qualcomm (San Diego, CA) in March 2017.

    Interview

    HR wrote saying the manager would call me in a few days for an interview. The HR did not say if this was an actual interview or to schedule an interview. She did not respond to any enquiries or clarifications (others have written about the rude incompetent HR).
    Turns out this was to schedule an interview but I wasted my time and energy wondering if this was an interview. Shame on HR.

    The manager scheduled a phone interview and asked me to answer some (not very well thought out questions about my background).

    During the phone interview (1.5 hours) the manager rambled on circumspect about why I had taken time off and programming experience. This is not a very high profile position and the manager was trying to hire someone who had both current hot skills as well as olde 19th century ones that she herself used. She asked if I would interview locally in Silicon Valley before they fly me over to which I promptly agreed.

    I never heard back after that. Not a courtesy from either rude hr or the manager herself. I didn't bother to ask either. This interview was the typical scenario where employees don't know much especially with regards to the latest trends but hypocritically set a very high bar for new hires. Didn't lose much sleep over this since I didn't expect to learn anything from anyone there least of all the old mothball of a manager.

    Application

    I applied online. I interviewed at Qualcomm (San Diego, CA) in February 2017.

    Interview

    2 round phone interviews and onsite. It makes me angry to interview with them. They are not nice at all, and they ask some questions that make you do not know what you need to answer. They seems to have racial discrimination.

    Difficult Interview

    Application

    I applied online. The process took 5 weeks. I interviewed at Qualcomm (Boulder, CO) in February 2017.

    Interview

    2 weeks after applying online I was contacted by the hiring manager for a technical phone screen. We went over pointers and simple function design/testing on a shared word document. 2 weeks later I went in for a full day interview at the Boulder campus. There were 13 other candidates there doing the same thing. I had (4) hour long technical interviews with different members of various teams and (1) half-hour long interview with HR. They fed us lunch and did a brief recruiting presentation. 2 weeks later they sent a generic email stating "Although we were very impressed with your background and qualifications, we are unable to offer you a position with Qualcomm at this time."
    Overall it seemed like they were more interested in finding book worms fresh out of school with no practical working experience than someone with actual embedded engineering experience.
    Make sure to study linked lists, linked lists, binary trees, and more linked lists because that is all they seem to care about!
