Exposure to big-name technologies (mostly related to SAP) and work with global clients. Excellent health insurance. Tuition reimbursement after you've been with the company for a year. Management has an open-door policy that actually feels open-door.
Cons
Professional growth slows after 3-4 years if you want to move beyond programming or leading small teams. "Customer service" culture feels servile. HR is too forgiving when administering disciplinary measures.
