Pros
I actually worked there from 2009 - 2013.
Upon joining, I had no experience in the telecom industry. Nevertheless, they put their faith in me and trained me where I was eventually promoted from senior associate to manager. After having worked at a number of places since, I can honestly say that pureIntegration is the only place that I would ever consider boomeranging back to. I enjoyed the many short-term projects that I worked on, each one of which providing me with some learning opportunities.
Cons
I wish that there were more junior level employees there that I could train and mentor and hone my management skills
