Pros
There are many challenging problems to be solved at eBay, which can make for intellectually stimulating work. Also, though the talent level does vary, there are many smart people within the organization who are fun to work with by and large.
Cons
It all starts at the top and eBay is fundamentally lacking in leadership or and vision. The Company is facing enormous strategic challenges but no one has shown me a coherent (and credible) plan for addressing them. Sorry, but "Trust, Value, and Selection" and "Deals you can talk about" just doesn't cut it for me. The people who run the marketplace business have demonstrated time and again that they don't understand technology, product development, and the core problems eBay's site, which leads them to seek quick fixes instead of demonstrating the patience and fortitude to address the big problems which won't deliver short-term benefits.
