Looking at my LinkedIn network of over 200 people, most people have been at more than one organization. If you take a random sample and interview you are bound to hear politically correct stories like

• I wanted more money.
• I felt under appreciated.
• I did not get along with my boss.
• I found a better opportunity.

Or you might find out that the person felt like they had their soul sucked out by Dementor kisses. Glassdoor.com is the place to air their filthy laundry about employment experiences anonymously. Registered users can review their previous position and talk about the benefits and gotchas of the employment experience. Registered users can also see the salaries for various positions within the companies.
