You're just a number. - Coach T-Mobile Employee Review

They will exploit every ounce of energy out of you. They will keep shoving work on top of what you already do and you won't get paid extra. Zero opportunity to move up. Only if someone happens to quit or die, then there will be that one position open, but wait... The position will open as an internship (Without the pay). After months or years of internship, you'll be interviewed where your performance will NOT be taken into consideration. You will only be able to get the position if you've been "friendly" with your bosses and they like you.
