Yet somehow this guy wormed his way into interviewing her. Someone let that happen, and someone gave this guy interviewing responsibilities.
First step is awareness, then next step is recognizing there's a problem. Your comment stops at the first step.
I meant no implication about it being acceptable in small companies - it is unacceptable everywhere.
Small company, he's a programmer - primary interviewer is in a relationship (last candidate said 'yes') - asks another technical interviewer if he's interested in this candidate's headshot. Happens all the time in startups / small companies.
My guess is about as feasible as yours, no?
I'm not discounting the possibility of your guess, but I have never experienced it personally, and I would have a major issue working with anyone who behaved in this manner in a professional environment.
