Data Domain Pre-Sales Engineer interview questions

THey started with 2 phone screen interviews, I was then invited in for 2 face to face interviews with managers, and 1 with a potential team member. If I would have been invited back for day 2, I would have met with a sales mgr and to give a presentation. They were very friendly and causal interviews, they did stick surprise tech questions in the middle and they did catch me surprise. I was surprised that I wasn't invited back for day 2. I wish I would have gotten some feedback, I would have liked working there.
