Linden Lab Senior Web Engineer, Back-End interview questions

I applied through their website. Process took about 2 weeks. Was contacted by HR Manager via email and asked to do a tech screening with their tech lead. Tech screening was via phone and lasted about 30 minutes. Was flown onsite to their office in San Francisco where I met with the team the position would be working with. Was given a tour of the office. There were 7 back to back interviews with a break in between for lunch. It was basically to check if I was qualified to work with them, they asked several questions for the white board. I was told about a week later that they chose to go with another candidate. The whole experience was really exhilarating.
