Pros
Discounted product, access to great speaking events, state of the art training facilities, beautiful campus. Great projects if you can stay away from speeding trains/buses, and getting thrown underneath them.
Cons
Youth culture - if you're over 30, people try to act like they're 22. Only athletic white males rise to leadership. Very political - difficult personalities and unclear routes of mobility. Cutthroat, and seduces people with the lure of the brand and offer sub-market salaries. Work-life balance varies by team. Management can allow or deny flex-schedules and telecommuting, as they deem appropriate. Healthcare coverage average - even on premier plans, expect A LOT of co-pays and co-insurance. NIKE is self-insured as their employees are "generally" healthier than other companies. Remember, people under 30 generally don't get sick outside of ACL/sports-related injuries. Looks great on the resume but be prepared to have to fight tooth-and-nail to stay relevant. Not for the faint of heart or over 30 crowd.
