SSL Systems Engineer interview questions

Applied online and followed up through a career fair. Started with a call from the hiring manager of the group. Asked a bunch of questions on resume and why I want to work at SSL. I explained all the experiences on the resume with technical terms and concepts to show my understanding. Later set an onsite interview, where they paid for flight and car rental. 4 hours interview including lunch with the hiring manager and his group. Another 2 hours with neighboring groups. One more 30 minutes presentation on a technical topic. Interviewed with total of 8 people. Followed up afterwards and got the offer. Great people, great culture, but I also had other offers. The pay is not that great for Silicon Valley.
