LinkedIn interview questions

I was contacted almost immediately after applying to the posting as they're growing fast and anxious to fill the job. They are upbeat and passionate about the company, but a bit full of themselves due to their success. Email turndown from HR person -- a complete turnoff after going to 3 rounds. Very disappointing given that they met me in person. Also, one of the interview rooms was as cold as a meat locker which also upset the sr management I met with, but we stayed in the room.
