Mixed - love it and hate it simultaneously. For a corporation, it's amazing.
Pros
The work environment is casual and there are lots of little perks (product, snacks, company-sponsored parties/events, discounts), an amazing and beautiful campus to come to every day. There are a lot of intelligent, ambitious and entrepreneurial types of people to work alongside. The CEO is amazing with an untarnished and highly-regarded reputation around campus.
Cons
The parking and commute is a total nightmare - Portland and Beaverton traffic is extremely congested every single morning and evening and working from home is not an option on my team. The cafeteria food is overpriced and uninspiring. While the people are some of the best I've ever worked with, too many people are self-absorbed and full of themselves and have the attitude/demeanor that they're saving the world while looking oh-so stylish. It's actually quite entertaining when it's not completely nauseating. A lot of waste happens at Nike - from massive amounts of product waste to extravagant & ridiculous spending amongst some teams, VP parking spots that sit empty while the rest are packed like sardines everywhere else, travel plans that change on a dime (and significant dollars lost in the process), and so on. Very difficult to push through the glass ceiling and walls at Nike.
