Pros
Unlimited PTO and flexible schedule, depending on your department you could be working with some of the most intelligent leaders in the industry. Great company parties!
Cons
Where do I start? I once read a glassdoor review that stated "Medidata where careers go to die" I didn't get it for the first year or so. Now if I could go back in time I would have ran and never looked back. Managers who are well educated and great leaders usually move on quickly leaving highly unqualified, unskilled tenured employees to take the reigns...and they are given a book on leadership and left alone..it's complete and total laziness on behalf of the C level leaders. HR is the WORST, I've seen them look the other way on several sexual harassment and general toxic workplace cases stating "that's how guys talk" and then saying if you have any concerns fill out this survey. They LIVE for glassdoor reviews which they write themselves regularly. Would NOT recommend!
