It started with an informal chat and then I was asked specific questions. The overall tone was friendly and it felt like a chat the whole way through. It lasted for an hour.

Interview was standard fare. Interviewers were friendly with a genuine interest in what I had to say. What let the entire process down is that, despite making it to the last round, you are sent a generic rejection email that simply states you will not be receiving feedback. This I can understand generally - but at the final round? It was a little cold, a short line or two wouldn't have gone amiss.
