Pros
Some good people with strong values and high integrity. Work life balance and focus on holistic development of staff. Recognizable brand name is still good on the CV.
Cons
I worked at other very high profile Silicon Valley tech companies and found LinkedIn to be very dysfunctional, especially the senior management team. A lot of ego despite the internal propaganda that there isn't. I also found LI to be highly political and not focused on creating the best results. Senior leaders in the US including the CEO and his immediate team simply are not great business people (look at profitability over 10 years - and Lynda, the latest in a long line of gaffes) and focus too much time on their image within the company and externally. I've personally encountered racism and gender bias and when it was raised to HR, some action was taken however nothing ever came of it and no changes were made. To be fair I think there are some great teams at LinkedIn, however these are not the norm and what you will likely experience, should you join LI, is a dysfunctional environment where it is very difficult to get things done and make a substantial impact. Most of the really smart, great men and women I knew at LinkedIn have moved on or are looking to move on.
