      Pros

      Met lots of great people there. That's about it.

      Cons

      I wasn't trained trained for months for a start and it was due to lack of upper management. I then went through a serious health crisis and HR treated me like I was lying and deceiving them. I have since leaving had to spend weeks in the hospital.
