    Average Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at Qualcomm (San Jose, CA) in May 2016.

    Interview

    Hiring manager set up the interview. Had a telephonic and got an onsite the next day. They asked me to fly in as soon as possible. Interview process was good with design questions, CDC, logic design etc. I got good reviews during the interview and I gave most of the answer correct.

    After that there was no communication, and later on I heard that they had already sent an offer letter to someone else before they interviewed me. This was a complete waste of candidate's time and QC's money. I hope they at least provide the feedback to make it worth my travel.
