I had 2 90 minute technical sessions, working through some toy problems (typical algorithmic type problems, basically little games). We started with working out some basic bits on the whiteboard and then actually implementing them in the language of my choice. Bring a laptop set up/ready to go because there is not a lot of time. There was also a 60 minute Q&A with a senior lead and a 60 minute Q&A with the most senior person in the Austin location. The first mostly asked me questions about myself and the 2nd mostly wanted me to ask questions, and explained some of what they do to me. There were no "gotcha" questions, no puzzle questions, no "why are manholes round" or "how many violins are then in New York". The programming problems were straight forward but obviously designed to show basic understanding of how to program. The non-technical interviews were mostly, I think, to see what kind of person I am, what I like, what I might need from an employer,etc.
