Pros
They legitimately want to remain number 1 in the industry. If job security is important to you, then you definitely want to work with people who have a clue. Their is a healthy paranoia around staying number 1 and targeting seemingly unachievable goals (but somehow always achieving them).
Cons
You will work hard. You will not be able to slack. Slackers don't last long. If you think you can "work less but work smarter", this is not the place for you. People here are both smart AND they work hard. That's not to say their isn't a work-life balance. It's just that slacking is not culturally acceptable or tolerated as it is in other companies. Want to "ride it out" to retirement? Again not the place. As long as you work here, you will work hard, but also contribute to great things.
