    I had two interviews, and both were on the phone. One interview was with a manager; second interview was with a software engineer. The manager asked me some high-level questions about my background, experience, and interests. The software engineer asked me a couple of (fairly simple) technical questions.

    Interview Questions

    The process took a dayinterviewed at NVIDIA in October 2010.

    Interview Details

    My interview with Nvidia consisted of a phone interview, a programming test, being flown out for a day of interviews on-site, and then being flown back out to interview with a second team.

    I applied for the job through a friend who works there. After interviewing with his manager I was asked to complete a programming question via e-mail within 30 minutes and send him the response. This question was designed to test my knowledge of memory management and the C programming language.

    All arrangements were simple and handled over e-mail with the recruiting coordinator. They made a reservation for the rental car, hotel, and airline tickets, and I had to pay and submit the hotel and rental car for reimbursement along with gas and meal charges.

    I interviewed with 7 people during my first trip out and was asked a variety of technical questions from programming, to systems architecture questions. I was also given a wide opportunity to learn about the company, the product I would be working on, and what the culture is like at Nvidia.

    I was declined an offer from this team based primarily on the time frame that I would be available on and the fact that they were looking for someone to start almost immediately and to ramp up quickly, but I received an offer to interview with a second team within the company that was much more established.

    For my second interview I met with 3 individuals from the new team and it was very similar to the first time. Plenty of technical questions and opportunity to ask about other aspects of the company.

    I would highly recommend you be familiar with C, developing on multi-core systems, and have a very good base in UNIX systems programming.

    Interview Questions
    • Implement a linked list structure and insert routine in C.
      Make it thread safe.
        Answer Question
    • Implement a function for compare and swap in C. Use this function to implement linked list insertion. How could you take advantage of hardware caching to implement this.   Answer Question
    • Implement a reader-writer locking system.   Answer Question
    • Implement the function strstr which returns a pointer to the first occurrence of one string within another.   Answer Question
    • Implement a function that takes a list of signed integers and looks for the consecutive subset with the highest sum.   Answer Question
    Reasons for Declining

    I declined the offer based on the fact that I had a similar offer from another company and I had overall heard better things about the on-boarding and ramp up experience with that company.
