To the OP, what you need to read is the Jepp Airway Manual - General. This has what you need. Forget commercially available books that may or may not have technically incorrect information. Why not ask your flying club if they have a copy for you to read/borrow if not in use?
Never heard of Jeppesen volumes for interview preparation.
It's not uncommon, RB.
Be careful of certain posters offering advice on this anonymous forum, most of them will not even have attended a pilot interview by virtue of the fact they do not hold professional licences (or even private, for that matter) If the airline has stated that questions will be asked based upon this document, then that's probably the best one to study, one would think.
This may be of some help, from a quick google. It's not current, be advised.
