The QA is really interesting. Most of the questions I felt he handled well and showed that he has knowledge of the domain. Two questions in particular stood out:
Q: How can I, as a developer, get my hands on the expensive software suite?
A: Come talk to us. We can accommodate developers who are willing.
This may have been some early input for him to think about sdks and the philosophy of providing developers with tools early on.
Q: What is your view of transactions on the web?
A: We don't think it's a technology problem. It's more of a social/business problem
He was clearly wrong on this one, with the advent of cutting edge technology companies like PayPal and Stripe that followed.
