My biggest indicator has always been, "do they do what they say they'll do?" If they want to meet for coffee and offer to buy you that coffee in exchange for your time, do they do this without you prompting them? If you end up buying your own coffee, and they simply forgot, do they acknowledge it? If they say they will email/phone you by a certain time, do they do this? If not, and they eventually do get to you, do they acknowledge/apologize for not keeping their word? For me, to quickly find out, it always come down to these little things. Sure, people forget to call/email/buy coffee all the time, that's acceptable. But, do they take accountability for that slip? Do they take responsibility for it without you prompting them? If the little things are handled professionally, I've never had an experience (yet) where the big things aren't...
