I think if a company has good answers to these questions, then they aren't really a startup. More often than not, if they're hiring you (being quite senior) it's because they need you to do all those things. But I do get where you're coming from. In my experience, it's better to ask about the team and its CTO to understand how decisions get made, and if the team is capable of recognizing quality. I don't care if CI isn't in place when I join as long as the team recognizes its importance and knows they need to get to it.
