    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!

    Average Interview

    Application

    I applied online. The process took 3 days. I interviewed at Qualcomm (Boulder, CO) in October 2016.

    Interview

    A technical phone interview was set up within a few days after I applied online. I was mostly tested on my knowledge of C programming and embedded systems. An on-site interview was set up within the next few weeks. This consisted of four 50-minute technical interviews with people on the team, lunch and a HR interview. There were questions related to topics like data structures, memory management. The interviews were fairly challenging. There was some C programming and problem solving on the white board. Overall, all the interviewers were all very friendly, professional and made me feel comfortable. I was very impressed with the atmosphere and the culture in the office.
