> This is completely acceptable. When was the last time you saw any job seeker seriously enquire about such practices in interviews or at the application stage?
Well, this is not something you can safely ask in most interviews. Also, while there's some sort of HN/hackerdom fiction that the job seeker holds some power during the interview, for most job seekers the interview is strongly imbalanced towards the interviewer. So asking clever questions during the interview is risky if you're desperate for a job.
agree - every time you ask a "clever" question you're increasing the risk it will be mis-interpreted, and also giving the interviewers a chance to pass. You may think you're being intelligent, honest or candid but it can easily come across as cocky, confrontational and (for lack of a better term) "off". I've passed on candidates for all of these reasons.
