    Software Engineer Audio DSP Interview

    Anonymous Interview Candidate

    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

    Neutral Experience
    Difficult Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Qualcomm (San Francisco, CA) in July 2016.

    Interview

    Telephonic Interview, along with a screen sharing software required for coding.
    Received a phone call first, started with my introduction, then directly jumped into the interview process.
    Questions were not too easy, not too difficult. This position was considering 0-2 years experience. I didn't get this position, because I'm a college graduate.

    • Interviewers asked most of the questions from the resume. Also a few questions related to fixed point arithmetic (Q representation) were asked. Also was asked to write a program that involved bitwise operators in C.   Answer Question

    Average Interview

    Application

    I applied online. The process took 2+ months. I interviewed at Qualcomm (San Diego, CA) in June 2013.

    Interview

    Submit my resume online, and after one week get a phone interview about one hour. Most of the phone interview are signal processing related basic questions such as how to detect the voice pitch, how to do adaptive noise reduction, filter designs, etc.
    After two weeks, get an invitation for on-site interview in San Diego. I met total 7 people including the recruiter at the first. One hour for each person. The rest of them are engineers including the manager in the group. Basic signal processing questions are asked and I feel I am doing well. One of them asked some coding problems and asked me to write the code on the blackboard. The problems are very basic such as reversing a linked list, and matrix operation, etc. However, I think I am not doing well in the coding questions, which is probably the main reason of the rejection.

    Interview Questions

    • All are basic signal processing questions, no surprisingly unexpected ones.   Answer Question
