Been to 3 interviews and had 3 offers so must have done something right.
I took my logbook, licences, medical, r/t etc to the interview but I also made decent copies and took them with me as well. When they asked for docs so they could photocopy them I presented them with tidy copies of the lot. You may think this sort of thing trivial but you don't have long to impress in an interview and showing some forethought (Notice-Understand-Think Ahead in Nigel-speak) isn't going to do any harm.
