Pros
Medidata is a team driven, accepting and diverse company. Compensation is good, great perks (unlimited PTO, work from home, Employee Stock Plan, Game rooms and travel) and a ton of opportunities to grow in a forever changing environment. Not unusual to see someone promoted to Manager from within.
Cons
You will get burned out if you let yourself work long hours and weekends. Focus on work/life balance. I feel like remote employees are often overlooked for promotions due to their absences.
