I did a little work as a developer for Verizon's ecosystem back in 2007. Let me just say, from what I could see, they were a huge, bureaucratic company without a single redeeming cultural trait. The managers seemed like a bunch of frat boys who had been raised up into positions of authority through some inscrutable lottery, and none of them seemed to possess an iota of analytical capability or human management talent.
I left that position and later worked for a bunch of tech startups and larger companies that, while not perfect, at least had enough good people in them to redeem my view on the human race.
I cannot imagine why anyone would actually work as a mid-level worker in Verizon unless you had absolutely no other options in life.
