Pros
Gartner tries to hire only exceptionally talented people, so it was really nice to work with a high caliber of peers and colleagues. It's a reputable brand.
Cons
Gartner pays sales people a pro-rated commission rate until a certain percentage of variable comp is reached. This is always a surprise to every new hire, and depending on when your portfolio's existing business renews, you could have small commissions until Q3/Q4. Leadership is all born from within Gartner, so their vision is very narrowed of how to manage a healthy sales organization. The culture has continued to decline over past year, and the sales management approach is intense micro-management of your every client email and presentations. If you are a sales person early in their career, this type of coaching may benefit you to cut your teeth. It's a great product but their research is only strong in specific areas. The product marketing team has made it very difficult to sell higher-priced products that clients would truly value and be easier to retain business. Their product model is "group membership" removing ability for clients to buy just one research license. Clients have grown frustrated. Gartner leadership is all about their brand, and not their people. People are extremely dispensable, and the churn for sales, delivery teams and HR is very high globally.
