My answer was no, after which they said the position was for XenDesktop, no XenApp. I later went back to the job description and in fact it still stated XenApp, not XenDesktop. Really odd and uncomfortable. It felt like a bait and switch and set a really bad tone for the rest of the interview. One of the 3 people interviewing me was about as unfriendly as they get. Because of him and the suddenly-its-about-XenDesktop I knew I didn't want to work there. Unfortunately, I didn't handle it well (should have just ended the webex), and it was the worst interview experience I've ever had.
