    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

    Difficult Interview

    Application

    I applied online. The process took 2+ months. I interviewed at Qualcomm in April 2017.

    Interview

    I applied through their career website, got a response within a week for a phone interview. Phone interview was a lot focused on my resume, about the project​ and technologies I worked with. Within 10 days I got an on-site interview invitation. I interviewed with 6 different people, 3 engineers, 2 manager and 1 HR. I prepared using Glassdoor and studied over things mentioned in requirements. It was really good experience, everyone was really cool and that helped me to not freaking out as I'm usually nervous.

    Interview Questions

    • Questions about my projects, some programming which you should be able to do if you are working on competitive coding.   Answer Question
