Pros

Collaborative culture, support and ongoing product knowledge opportunities

Cons

Despite what they say, you’re just a number. They’ll RIF anyone and won’t tell you before they cut off access to your laptop. Gartner leadership is like southern hospitality- they’ll be nice to your face but they’ll disregard you as soon as you walk away.
