Quite right. Other problems include HR is not on your side, you may need references, etc. I'm not sure how exit interview results overlap with glassdoor reviews. Do people feel glass door offers more anonymity? Perhaps people secure their next job then write a negative review once "burning bridges" becomes less consequential ?
