First step was a phone interview with a recruiter that mostly talked about my past experiences and why I am interested in SIG. The recruiter also asks if you are familiar with a bunch of CS topics, and I think this would affect the questions you are asked in the next step.

Second step was a technical phone interview with an engineer. Most of it was general technical problems about things listed on your resume. I have an EE background, so most of my questions were about low level programming such as caching, memory, etc. The only programming problem asked was how to implement fibonnaci.

I did not get past the 2nd step. I believe the 3rd step would have been the final onsite interview. I thought I did well on the interview, but I guess not. Sadly, they do not give feedback.
