I`d spend at least 30mins of the time allocated chatting to them. As well as how they play, you need to get on with them. Agreed a 30min chat won`t make the decision of best buddies, but you can usually get an inkling of their character. Ask about transport, work, family, other musical commitments, gear, willingness to travel etc.

This is spot on. It will take you just five minutes to establish whether or not they can play guitar, but five months to learn whether or not you actually like being in a band with them.
