I had several long phone/skype interviews before a face to face on-site interview. The day was only partly filled with interviews and there were plenty of people with whom I needed to chat with and I would work with. Still they just left me in their conference room. This was after a lot of haggling over dates to meet schedules/ Very weird vibe. Staff that would report to me looked like scared inmates. Very defensive, concerning. The presentation to them, a ppt, was videotaped - like some legal deposition. I have no qualms with public speaking but it was weird, again.
