it's nice if they have a current bfr with an instructor you respect. if so, then it may be a half-hour flight, almost a technicality. if they're an unknown, i dig into their ground knowledge of charts, regs like 91.103, ask the type of flying they do mostly, the afm. ask if they use checklists. if i see positives here, i can expect a flight of less than an hour, otherwise longer..and may not happen same day. i'm verrrry rarely impressed with a pilot's flying skills, but i can be impressed by solid aeronautical knowledge.
