I've had two exit interviews and I was brutally honest on both, and both times I ended up forming stronger relationships as a result of my brutal honesty. The first time I left for significantly more money, so it's an easy way to leave on good terms. During my exit interview, I gave honest feedback about the pay-scales and where I thought pay should be. After my departure, my entire team and the incoming new hires were given pay raises to exactly what I discussed with the hiring director and manager. While the author may argue that this doesn't benefit me directly, it benefited me indirectly in that my colleagues will remember me as the guy that helped them get more money and my superiors remember me as the guy that gave honest feedback and left for more money.

The second time around, I had a boss who I felt was a terrible leader and micromanager. I actually ended up having 3 exit interviews.. one with my boss, which was very short and I told him how he and his management style was directly the reason I was leaving. The next two interviews were with the CEO and an investor in the company where I was once again brutally honest about my bosses management style and some other negative feedback about the state of the company. While I may have burned a bridge with my direct boss, I formed a good relationship with a CEO and PE investor who even offered to help place me in any of the companies they invest in if I chose to stay with the company.

It's great to give your take on something, but the assertive titles on an opinionated generalization are getting annoying.
