It is very formulaic. Not very conversational. Managers pretty much have a good idea of who they want to hire so interviewing can be seen as a waste of time. Lots of situational questions are asked. Be sure to have extensive employee relations experience or they will just go through the motions with you and won't consider you at all.

Very impersonal and corporate - interviewers were chatting about a mutual colleague for several minutes before the interview got started and they finally introduced themselves. Went through two full interviews and didn't get anything back - had to follow up about status of position after several weeks.
