Pros
Gallup's brand is its number one differentiator. Many Consultants are intelligent people who believe in the brand and will do whatever it takes to close deals. Lots of autonomy in your role attracts a certain type of personality.
Cons
Burnout, burnout, and more burnout. Lack of diversity in the consulting side. Go-Tos have too much power over the trajectory of your career. Consulting position has ZERO work-life balance. You overwork yourself to make the Clifton family richer - they're billionaires! Go-Tos steal your ideas and pass them on to their favorite employees without giving you any credit. So many people left the company, it's embarrassing. They only care about selling their dogma in books and standard tools that have zero innovation. Company is based in Omaha, need I say more about having a small-town company culture that does not appreciate diversity. Way too Jim Jones-like for me.
