I only recently came across this idea; watched a video on it, which basically pointed out there was nothing to be gained, and plenty to lose, by doing them. Makes me wonder though, isn't there a risk of losing something? I've seen a number of people come back to the company I work out, so wouldn't refusing to do an exit interview be akin to burning the bridge? [Yeah I know, HR would be foolish to hold it against someone, if someone is qualified for the job and a good fit, using this refusal as a reason to not hire.]
