Most early stage companies would have had terrible answers to these questions. Including Facebook/Google/Uber/Amazon. Which just indicates that it might not have been an ideal role for you which is fair. Being the first 2-3 engineers at a startup is not everyone's cup of tea. The risk in most cases makes no sense for a sane individual. Your questions indicate a sense of "safety" that an engineer might want from their next gig.

They might not even be able to hire a Senior Engineer in most cases. Maybe you wouldn't even want to talk to an early stage startup at your current seniority level.

Having said that for anybody who really wants to join an early stage startup the only thing that should probably matter is what is it that you're trying to do and how can I help you reach your goal? Will you be able to pay me enough on time and for how long?

CI/CD can be set up pretty quickly with modern tools. You can of course spend time over engineering with lots of different environments that you can create with scripts but just setting up a basic pull request->build->run tests->automatic deploy->promote to higher environments is like one days work for one person these days.
