The fact that you're thinking this way and have these specific questions already means you're in pretty good shape out of the gate.
Other people have covered the sensible additional questions and issues pretty well I think.
Someone's perceptions of how well they follow best practices, et al, are almost always going to be better than they are. What I think you really want to hear is "not as well as we'd like, but we're pulling in that direction." More likely you'll hear "Yes, We're leet!" in an attempt to impress. Which, meh, they're human, it's what to expect.
You could cut through a lot of bullshit if you could get them to give you a specific real life example of a couple assignments. Reaction to that kind of a question will tell you volumes.
