recruiters always benefit from full disclosure and honesty. They have nothing to hide and a lot to gain from transparency. Hiring and seeker sides are to varying extent cautious about “showing your hands” or disclosing damaging information. It's instructive to compare the hiring and seeker sides.

It's reasonable to ask a candidate “what are you looking for” but if candidate discloses everything (there's no verifiable truth here anyway), it hurts the candidate.

It's unfortunate if a candidate works for a brief period and quits without producing any value.

It's morally and socially unacceptable to lie about job history — verifiable facts.
