Pros
It's not unusual to find tenures of 10 or 20 years here, or people who decided to try something else for a while but then came back to Gartner. At the same time, the company is growing so there are always new faces and new ideas, and receptivity to fresh perspectives. The simplest way to say it is that Gartner is a company that does the right thing. The culture is collegial, the politics are kept to a minimum, the people are smart, and the best ideas usually win. It is scrupulously ethical in its business activities, respects its employees and treats us fairly, supports career and personal development goals, all while encouraging us to achieve more. I've been here over a decade and still love it.
Cons
Strong bias toward working in the office
