If you have a favorite candidate and are trying to prepare that person (per the related podcast episode), should you be forthright and let that person know where he stands with you at this stage, i.e. let him know he's is your top candidate? Or is it better to hold your cards close and not give them what could turn out to be a false expectation?
What if you have a second choice the boss might also interview? Does that change what you might tell the preferred candidate?
Should you let the top candidate know that the boss will be interviewing one or more other people? Is that of any benefit for him to know? Or does that, effectively, amount to playing games with him (at least from the candidate's point of view)?
