If they haven't gone over it in complete detail yet, ask them about their development cycle. Do they use Scrum/Agile? What version control do they use? How do they do estimates? If they use git, how do they do branching? Do they do testing? If so, do they do unit testing, continuous integration, etc.? Do they have a QA team? Revealing questions: 1.) What happens when the estimate is off? Does it happen often? This should give you a hint as to how much overtime you'll be working. 2.) Do you like working here? Look for what their reaction is. If they pause or stammer, it can be a red flag. 3.) How many weeks of vacation did you take last year? Some companies have "unlimited" vacation time policy, but you might feel awkward taking 5 weeks if everyone else takes 3.
