I applied online and the process took 2 days - interviewed at Qualcomm in January 2010.

Interview Details – Received a phone call to schedule a phone interview. Then received a phone call with 2-3 engineers and answered some technical questions. Subsequently scheduled an on-site interview.

There were 4 sessions each about an hour with 2-3 people. Questions about micro-architecture and logic design were asked. Variable-width adder, pipeline control, cache configuration, multiplier, etc.

Interview Question – Design a variable data-width parallel adder that can optionally be signed or cosigned using a minimal number of bits.   View Answer

Negotiation Details – I was able to negotiate but decided not to. The process of getting an offer through the hiring system is rather long (2 weeks) so negotiations would take a while. My advice is to ask for a higher number than you'd be willing to settle for in the first place.

I applied online and the process took a day - interviewed at Qualcomm in April 2008.

Interview Details – I had several phone interviews with Qualcomm for their engineer positions but failed to score an on-site one mostly because I wasn't very prepared for their technical questions. So make sure you got the basics down before applying. As much as I remember, those interview questions cover lots of C fundamentals such as pointers, function pointers and function calls, as well as other computer science knowledge. Good luck!
