Pros
It's the growth engine for eBay and there's a lot of investment from the execs in growing PayPal even faster and making it stronger. PayPal's in a very dominant position in the online payments industry, which is definitely a plus. There's also a lot of cool projects for products in mobile, developing countries, microfinance, etc. The people are smart and motivated, and they have some of the eBay friendliness to them. I found everyone to be very helpful and open when I requested their time to get input on products I was researching. The benefits are great, even pet insurance. I rode the CalTrain down from SF and they subsidized that and picked everyone up with shuttles.
Kontras
It's in San Jose. It's nice for some people but not for me. For my personal life i wanted to live in SF, and that meant a 2 hr commute each day on the Caltrain, or i could have done the 101. It's a big organization. If you're used to getting things down quickly with little overhead then this place can be stifling. There are many layers of management to get through to get anything done. Finally, it's a bank. When you boil things down that's what it is. So from a culture standpoint it's a bit confusing. People are friendly but not that fun (like their eBay counterparts).
