DSP Firmware Engineer (Wireless Modem) Interview

DSP Firmware Engineer (Wireless Modem)
Santa Clara, CA

I applied online and the process took a day - interviewed at Qualcomm in November 2009.

Interview Details – The HR took 2 weeks to schedule the first phone interview. The interviewer asked about my background, academic projects and past internships. Then asked basic technical questions about computer architecture, basic DSP, and few C questions. I fumbled and did not get any further interviews.

Interview Question – Swap two numbers without using a temporary variable   View Answer
