Vantaggi
Benefits are probably the best of any company that I've ever heard of and I'm not just speaking of health benefits and stock options. PayPal offers everything from tuition reimbursement to a free membership with Care.com.
Svantaggi
If you want a position outside of customer service, you must be prepared to work your behind off and deal with the politics of a large corporate world. And trust me, unless you're a college kid working towards a degree, you WANT to be out of customer service. In the position that I was in, I was one of five in the entire company supporting three rather large departments. I loved my job, but there was SO much drama and cattiness. People have been in these positions so long, it was like High School all over again.
