Exactly. I went to two airline interviews with plenty over the mins. My hours were covered so quickly that I almost wanted to talk about them some more but the interviewer wasn't really interested. You are a known quantity.

If you are neat, have a method to follow that airline's rules as you understand them, and aren't greedy...you don't have to over think this. Sometimes they want to just use the discussion as a way to see if you get flustered and how you deal with it.
