    Application

    I applied through an employee referral – interviewed at Qualcomm.

    Interview

    Interviewer was late and unorganized. Unable to understand what the interviewer was saying and asked questions on languages I'm unfamiliar with. Not a good interview overall. Interviewer didn't know who I was initially and called me late. I had to contact the recruiter.

    Interview

    Phone interviews. Interviewer was difficult to understand and seemed unfamiliar with some of the common software used in his specialization. The location and start date were impossible for me and we realized that in the first few minutes of the interview. I found the whole interview to be technically easy but was thrown off by the unprepared nature of the interviewer.

    Interview

    I went to the career fair offered at my school and dropped off my resume at Qualcomm. About 2 weeks later I was contacted by a recruiter who scheduled an interview for me on campus. It was a one time interview and I got an offer less than a week after. I got 2 coding questions and one puzzle. The first one was to identify bugs on some simple code. Second one was to return the most frequent character in a given string.

    Application

    I applied through an employee referral. The process took 6 weeksinterviewed at Qualcomm.

    Interview

    Put my application in through the qualcomm careers website. Got a quick response within a week. HR emailed me to give them suitable dates and times. I sent them my preferred slots for a phone interview, then next day HR replied with a selected time. The HR seemed very responsive and the interview was setup for the earliest possible date.

    The interviewer called me and started off with some basic review of my CV. I am in R&D, so a lot of questions and details about my projects, research. Then interview shifted to technical questions related to programming. One question was on software design, he asked me how I would go about developing a basic operating system/file system. I responded that you first define the objectives, get user/customer inputs. Define the structure, for example, you need a file system management module, display, user input, file editing etc. How would you tie these together (implement abstract classes to define API) etc. The interviewer basically wanted to see my thought process and how I approach this problem. Then I was asked to rate myself at C++, what were my weakness when it came the language etc. After about 45 minutes, the interviewer started talking about their projects and work. Gave me a chance to ask questions and possible start dates.

    Got a call for second interview, waiting on that.

    Update-> One month after first interview, I got the offer.
