Pros
Honestly, the cons absolutely outweigh any of the pros. Read my cons section further to gain insight into this. They give you a great salary, flexible work hours, and they feed you, but it means nothing if in the end, they kick you to the curb for having depression.
Cons
I worked here as an intern for two summers, as well as a contractor, and also offered a full-time position, which I accepted. I was supposed to graduate in summer of 2013 and start work shortly thereafter. However, I've been a long time sufferer of depression, anxiety, and insomnia. I missed my summer graduation date and instead graduated in December of that year, due to my health issues. I informed my former boss about my health issues, at which point he reduced my illness to being "sad" (demonstrating a complete lack of understanding of depression) and then proceeded to tell me that my full-time offer was rescinded. This company encourages a lot of physical health, and will even have pee color charts hanging in the bathrooms to tell you what healthy pee should look like, but does ABSOLUTELY NOTHING to help with mental health (unlike Google, which has programs specifically for mental health, because unlike LinkedIn, they actually understand the importance of mental health). I still have friends that work at LinkedIn, and they inform me that they are STILL doing nothing to this very day to assist with mental health. This is a company that will pepper you with gifts, treat you like a king, and make you feel like a part of the family, until you share that you have mental illness. I literally got care packages sent to my home while in school, with hot cocoa and LinkedIn travel mugs and sweatshirts and other absurdities. This company understands how to basically mess with your mind, but not help it. If you are a software engineer, and you have mental illnesses (you probably do, we're a wacky bunch), do NOT work for this company. They won't help you, and they will just kick you to the curb if you let them know of your situation. Go work for Google instead, since they actually help you AND understand your mental health issues. This company made me learn that honesty is really not the best policy. Thanks for that, LinkedIn. TL;DR: Company treats you like a king until you show mental health problems, they do nothing to help those mental health problems, and instead kick you to the curb. Do not invest your talents here, go to Google or Twitter or anywhere else, really.
