This list is missing the two most important [busines] questions:
1. How do you make money?
If you can't understand, or the interview can't explain, then I'd run away. This can also lead to interesting questions about risks, competitors, etc.
2. What's preventing you from making more money?
The answer that you want to hear is engineering effort. If not, you're (at best) a wallflower at the party. Don't be the chump that's at Goldman Sachs acting as a code monkey for the traders. Don't be writing code at a company (like Enron) which has its success based on digging holes in the ground.
I can dig up the slides if anyone is interested.
