    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!

    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.

The technologies that Qualcomm is involved in are cool and you get an opportunity to see where the electronics industry is headed in the future. I would say there's a lot of flexibility and job training, depending on what team you're on. There are really smart people at this company...for now. If you're in it for U.S. citizenship it seems that their immigration support is great, but you will work for it. The pay is okay compared to most companies.” – Full Review
