Their notion was: 1) We're there to find candidates, not improve people. 2) Time spent on someone you've eliminated is a loss. Cut your losses. 3) Think like you're talking to the police. Are you 100% sure you're not going to say anything that could be even remotely construed as illegally discriminatory? 4) Most states are 1-party-consent for recording, and even if it's an inadmissible recording, them having an interaction recorded can come back to bite you if they use it to jog their memory to perfection.
