Pros
Couldn't have asked for a better experience! Amazing food, free gym / fitness classes, monthly InDays to do anything you want, inspiring CEO, lots of support available to interns, fun intern events (Disneyland trip, paintballing, speaker series, etc.), amazing culture, good pay, sooo many perks, the list goes on and on... They house the interns in the same apartment complex so it was really easy to meet other people, hang out after work, etc. This summer made me feel so spoiled; it felt like summer camp! I was worried that all of the other interns would be the stereotypical "CS nerd" type but that was certainly not the case. You can tell LinkedIn focuses a lot on culture fit and that is apparent in their hiring. I think the intern program is the perfect size. They keep it a little smaller than some other large tech companies which means more of the interns can get return offers. LinkedIn invests a lot into their intern program and it is very apparent.
Cons
Gained weight from all the good food! Looking back I think I would have preferred to work in the SF office instead of the south bay because it's a more exciting area if you're young.
