Applied online, went through a brief phone screening interview on basic linux questions. A few days later, went through a more technical interview with a linux tech, including some 'breakfix' scenarios after logging into a testing server. Another recruiter called a few days later saying they wanted to interview me for the linux support in the cloud division, so there was another technical phone interview and breakfix session with a linux cloud support tech. After this I was invited to San Antonio for some in-person interviewing, which included meeting with three groups of two rackers each, about 3 hours in total where we went over both linux questions and personality-type questions as well as some whiteboard "brain workout" exercises. After returning home, I was called by my recruiter to setup a skype video interview with some of the people that would be on my shift if hired. This wasn't a technical interview, it was basically a 'team fit' interview on personality. A couple of days later, my recruiter called and made an offer.
