Andrew's interviews are awesome and he's a super nice guy to boot, always willing to help founders out where he can. I remember listening to them on my commute to work with my cofounder years ago. Those hours in the car were a major source of early startup lessons. Mixergy is one of the best startup resources out there in my opinion and is worth checking out if you haven't yet.

PG's interview is still open even though it's over the premium membership threshold - http://mixergy.com/y-combinator-paul-graham
