Sledgehammer Games Artist interview questions

I contacted the recruiter at that time on LinkedIn, expressing my interest and showed my portfolio. The recruiter sent me an art test. The art test was fast, and I did lose sleep. Next I had a phone interview with an HR person, then a Skype interview with my lead. He pointed out some areas of the art test that could be improved. I made the improvements and resubmitted. Then I had a Skype marathon interview with 4 groups of 2-3 people, which in total lasted 2-3 hours. After that I received a job offer.
