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

    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.

    Difficult Interview

    Application

    I applied online. The process took a week. I interviewed at Qualcomm in January 2017.

    Interview

    First they emailed for scheduling a technical phone interview within a week. The interview experience was very good even though I did not perform well. He mainly asked about Operating systems and C. As I am from Electrical background, I did not have much knowledge about operating systems. The interviewer would give enough hints on the questions you fumbled. Its an easy interview for computer science majors I guess. It lasted for about 40 minutes.

    Interview Questions

    • It started with C questions:
      -storage classes in C
      -Dynamic memory allocation
      -Binary tree and its time complexity
      -different sorting methods, and asked to explain quick sort, time complexities
      -what is linked list, what is its time complexity
      -asked to write atoi function code using screen share

      Operating Systems:
      -what is a thread
      -context switching
      -inter process communication
      -preemptive and non preemptive process
      and other things which I had never heard before and don't even remember.
