Pros
Excellent place to start or build on your career if you're looking for experience or exposure to a wide range of businesses. Great internal resources for career growth.
Cons
There was a mantra of "the mission before the metric" but that saying has been completely hollow for the past 6 months. Metric squeezes are consistent and 10+ hour work days are normal to keep in line. The greatest criticism is Gartner does not practice what it preaches. Even taking research to management to suggest better ways of working or thinking is slapped down as the metric comes first, not the client. The lack of work life balance hurts. Flagging it with leadership is dismissed quickly. Talking upstream doesn't work. National R U Ok day passed the other day and too many people, myself included are not Ok. You're a number, not a person.
