Eff a diverse culture. Get your money and move to the next opportunity when it is time. You got Ebay on your resume now, all this stuff you concerned about will be non factors once you get the experience to make some real money. As long as you aren't in a role where you are being micromanaged to the point it impacts your performance than there isn't much to complain about. You're in the grind stage so you just gotta suck it up because I promise there are 10+ dudes in this thread worrying about little things like getting their worthless A+ certs who would rather trade places with you.
If this is what you actually want to do then you'd know that the annoying sacrifices will pay off (unless you plan on being in help desk forever).
This can't be emphasize enough. I'm sure there's huge room for growth and opportunities to learn at eBay. Its sounds like they value you as an employee so who knows what lies ahead if you stick it out for a bit.
