Pros
It's very hard to name a pro. I did enjoy working with a few people here, but the good are leaving in droves, and the company is struggling to keep qualified technical staff. There was a work from home option, was is fantastic if you want to avoid seeing the craziness.
Cons
Technology is not a strength of IMS, or Quintiles. Now having two poorly managed technical teams, does not cancel each other out. It compounds the problem. This place has more red tape than the government to get anything done. The only people who succeed in getting any progress made are those that are master manipulators. You don't know who you can trust, and it feels like everyone is lurking with intent to sabotage any progress being made. Too much trust is put into persons who provide little to no value, only because they are crazy good at self promotion. The company moves like molasses to even get started on any project. There are pockets of really good people that are highly under utilized. The process that was forced on everyone only stifles innovation.
