Pros
lots of great individuals to work with, can find a good team. for such a gigantic company they try to have a good culture, and do a decent job. some good "new" products, with the correct projects to address issues, consolidate network, and billing to be more competitive and agile (as agile as a $18B company can me). So working on the right things to move everything in the right direction, to stop the bleeding. At least they were when I left in 2014.
Cons
Contracting vehicles needed some work. some customers had to sign 3-5 different contracts with 3-5 separate bills from 3-5 different entities. Lots of not so great individuals, lifers, there were 2 people with 45+ years with CL. its a mix of old guard and new guard. everyone needs to embrace the new products + new direction. it is no longer a "copper" telco. mid level managers get worked to the bone. one peer was working 90-100 hours a week as interim director, but never offered the job or pay to match. very little time for mentoring direct reports.
