Get "Ace the Pilot Technical Interview" by Gary Bristow. It is very good and contains a great summary of your ATPL notes, in an interview question style format. It is aimed at an international audience, so you will need to refer back to your notes for JAA specific stuff on performance and law etc., but it is worth EVERY penny.
It won't help you on the "what are your strengths and weaknesses" questions, but will be useful for any technical part.
