With respect that's quite naive.
> 1) Being true to yourself is worth more than any of his purported wins
'Leaving a job that doesn't suit you' is the part where you're being true to yourself; whatever you say in the exit interview usually doesn't have a material positive effect on one's own life except possibly the chance to get some closure if things have been really bad - in such situations, however, I would say there is a less than average chance of achieving even that, otherwise maybe it would have been possible to work things out without leaving.
> 2) Be your own merit, and don't rely on others for references or goodwill
So whose name should I write down when asked for a referee? My own? As the article said, later in your career this is much less of a concern but when starting out and being an unknown quantity, every sympathetic connection is more valuable because you don't have many.
> 3) If every exit interviewee states that the CEO is a dick, that can't be ignored. She won't lose her job, but it's not going to do her any favours either
Sure it can, it happens all the time. Dick CEO will either find ways to rationalise the bad feedback, outright ignore it, or else the feedback won't make it that far up the chain as the interviewer values their own job and the CEO is a dick.
> If you get in trouble for telling the truth, that's not a company you need to be at.
Right, but... we're talking about exit interviews; by definition you won't be staying there and derive little to no benefit by being fully open even if things do change. The author of the post wasn't necessarily advocating lying unless there was no other way, just being economical with the truth.
> Also important; don't be a dick. There's a difference between telling the truth to constructive ends, and being a whiny critical negative contrarian.
Sure, that's always good advice, but it doesn't require total honesty; bland empty replies work just as well and don't trigger the kind of fragile egos that so often seem to make their way up the food chain.
