Senior Systems Engineer Interview

Average Interview

Application

I applied online. I interviewed at Qualcomm (San Diego, CA) in April 2017.

Interview

They contacted me two months after I applied online. The first interview was technical which I easily passed. Then I went onsite to give a talk and for further interviews. I did great in the interview and two weeks later I got an email from the HR that I passed the interview and got a pending offer. We even discussed numbers. The HR then stopped responding to my emails. I finally chatted with hiring manager and it turned out that they had given offer to multiple people. Very unprofessional. Qualcomm is taking its path down to a 3rd tier company.

Interview Questions

  • They asked general math, signal processing, and machine learning questions.   Answer Question

    Easy Interview

    Application

    The process took 1 day. I interviewed at Qualcomm (San Diego, CA) in January 2012.

    Interview

    Some basic probability/stochastic process questions about lossy wireless channels.

    The last question the interview asked was: "Suppose we make 10 packet transmissions per second over a wireless channel, the channel is lossy such that with probability 1/10 a packet transmission will fail. The transmitter knows perfectly whether a transmission succeeds or fails. When it fails, the transmitter retransmit the packet, until it finally succeeds. So what is the throughput we can get?"

    This was a VERY VERY simple question that the throughput should be 9 packets/second! The interview didn't agree and simply emphasized "because of retransmission, throughput should be reduced more than 1/10" repeatedly.

    Couldn't achieve a consensus with him after a long debate and that's it.

    Interview Questions

    • Given a wireless channel with loss rate 0.1, what's the throughput one can get with retransmission.   8 Answers
