    Embedded Software Engineer Interview

    Anonymous Interview Candidate in Arlington, VA

    Neutral Experience
    Difficult Interview

    Application

    I applied through an employee referral. The process took 1+ week. I interviewed at Qualcomm (Arlington, VA) in January 2017.

    Interview

    I got an interview call for Embedded Software Stability Engineer from their team which is based in San Diego. The call lasted for a brief 30 minutes. It began with a quick introduction by the interviewer about himself, his team and Qualcomm.

    He later asked me questions on C, RTOS and Embedded. The questions were conceptual and it took me an average time to answer them. I am hoping to hear back from them to proceed to next round of interviews.

    Average Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Qualcomm (San Diego, CA) in January 2017.

    Interview

    There are two rounds of phone interviews. HR arranged them to be consecutive for me, lasting an hour and a half in total, 45 minutes each. Basically talked about resumes and personal area of interests and ask questions while talking through. Questions are pretty random and are used to test the overall background of the candidate. Not many questions are related directly to the internship position I am applying for. My suggestion would be really focus on fundamental circuit design concepts, tradeoffs, know what you are doing in every step of the design process.

    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.

    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.
