    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.

    Positive Experience
    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.

They are trying to raise money and bring people to an office full-time, so I guess that will change. Very welcoming to new ideas.” – Full Review
