Pros
LinkedIn's company culture is one of a kind. I'm excited to go to work in the morning because I have the opportunity to interact with extremely intelligent people and because I'm still early in my career, it is great to be able to learn from such brilliant minds. The work/life balance of LinkedIn is something I cherish. Although I take the shuttle to and from San Francisco, I still feel like I have enough time to do the things I want to do. At LinkedIn, we're treated like valued employees. It's hard not to love your job when you walk around campus and always see smiling faces.
Cons
If you're not a self-motived person, LinkedIn isn't the place for you. There are a lot of distractions (game rooms, a band room, free food everywhere/all day, InDays, HackDays, classes to take, etc) and you still need to get your daily work done.
