My initial contact with Rackspace was over email where we set up a time for technical pre-screening interview. The time of the interview arrived but the recruiter called me later than she said she would. I was very impressed with the systematized interview questions, arranged into beginner, intermediate and advanced. If I didn't know the answer, the interviewer gave me the answer (which I thought was really considerate as that's a common post-interview questions "what was the answer to that question?"). At the end, she told me I had done better than expected. An interview with the hiring manager was arranged but ultimately fell through when I told them I wanted to work remotely.

First call is with recruiter then they schedule the technical screening. Once you pass that you go onsite for a panel. Mine was 4 panels and range between 2-3 people asking questions. Had to whiteboard some code and other were team fit questions.

HR first called in phone and asked for Java, SQL related technical questions. Then he arranged for two phone technical interview one with test team manager and other with architect head. Telephonic interview went well. They called me in person interview to their Texas, San Antonio location.
