Enterprise VS Regular corporate developer

Question

Ok, I "almost" lost a job offer because I "didn't have enough experience as an enterprise software engineer".

I've been a programmer for over 16 years, and the last 12-14 professionally, at companies big and small.

So this made me think of this question: What's the difference between a software engineer and an enterprise software engineer?

Is there really a difference between software architecture and enterprise architecture?

BTW: I try to do what every other GOOD software programmer does, like architecture, tdd, SDLC, etc.
