Pros
Pay and benefits were decent, people at the corporate level seemed like they cared about the employees.
Cons
The specific team I worked on was one of the most dysfunctional teams I've ever seen. Excessive reliance on tribal knowledge, very little useful documentation of anything (and a feeling that at least some of this was by design), poorly written test cases bordering on useless, optimizing for optics over getting the job done, and so much noise in email and teams channels that it was nearly impossible to find any useful information and frequent work on weekends to make up for downtime during normal working hours. It's hard to say how much of this was the client and how much was on the Amdocs side, but it is clear that whatever development process they were using was not working.
