    Software Engineer Audio DSP Interview

    Positive Experience
    Difficult Interview

    Application

    I applied online. The process took 6+ weeks. I interviewed at Qualcomm in June 2017.

    Interview

    I applied online and was called and emailed by two separate HR members to schedule a phone interview. The phone interview was about 45 minutes and was almost entirely deep technical questions on operating systems, concurrency, multithreaded programming, and embedded systems concepts. About a week after the phone interview I got an email to schedule the on-site. The on-site ran from 10:30 to 4:30 and was made up of 6 total interviews, 5 of which were technical with a mixture of staff engineers, managers, and directors/VPs of engineering. It also included a lunch interview where one of your interviewers buy you lunch then do a more informal interview while you eat. The interviews were a mixture of talking about my past projects, conceptual OS questions, and a huge number of C questions where you're either given a code fragment and asked to say what the error/output is or asked to write a C function to do something. You need to be really strong at C programming and the C language (scope of variables, keywords, all kinds of memory allocation) to stand a chance for a SWE position here, it's much closer to computer engineering than computer science. Only negatives with the experience was a bit of disorganization, I was contacted by two different HR reps for the same position, one of my interviewers didn't even show up, but other than that it was a positive experience.

    Interview Questions

    • Write a function in C to merge two sorted arrays into a single sorted array.   Answer Question
    • Given half a dozen C code fragments, identify the error or explain what the output will be.   Answer Question
    • DSP questions - how an A/D converter works, what the format of an audio file looks like   Answer Question
    • Deep dive into architecture/OS - how to detect page corruption, how to find the offset of an element inside a struct without accessing the variable directly, how to synchronize memory across two CPUs in a cluster.   Answer Question

    I applied online. The process took 3+ months. I interviewed at Qualcomm (San Diego, CA) in June 2017.

    Interview

    Applied online. After 4 weeks, HR reached out to me and scheduled a phone interview with the hiring manager. The next week, had a 45 minute conversation with the hiring manager. Basically just went over my resume and experience. A few days later, had a 2 hour technical interview (over the phone) with his staff members. The next day, HR reached out to me to get my availability for another interview. After I gave my availability, HR went dark on me. I followed up week after week for a month then eventually gave up.
