Vantaggi
At the time in my career, paid pretty well. They contracted out to some fantastic companies that I made good connections with. Benefits not bad. Bonuses. I learned how not to develop software. Then I was part of an effort to change that process where I could, but that meant little in the gigantic black hole of inefficiency that is Charter. If you're really good, you can advance quickly because most of the people you work with are totally checked out.
Svantaggi
Where to start. I was a highish level manager in the software dev organization. Have you ever worked on software at a company that is just peripherally about software? Spoiler alert: It's terrible. Charter is a cable company. Plain and simple. All the bad things you read about how terrible cable companies are? For the most part that doesn't really trickle down to working there, but it's plenty enough to make you hate everything. I had to quit because I felt like I hated humanity, and I didn't want to be that person. Bullet points: You're AGILE, but your code won't see the light of day for a year, if you're lucky. Five QA teams. Even if you're a code grunt, you're in meetings far more than coding. Management HATES that they have to pay for quality. They would replace you in a second if they thought they could pay that college grad 1/2 what you make for 51% quality. Absurd office drama. People scamming the company, people sleeping their way to VP positions, no-bid contracts to companies that a VP is on the board of. Always desperately trying to catch up to something another cable company already did. Do you really want to just copy Comcast's already crummy design? Revolving door of colleagues. Finally- you are judged by how much it costs them for you to produce a story point. Literally.
