It sounds like we're now back to mind reading the answer you'd like them to provide based on overly broad questions. That is a poor way to assess whether they know about a topic. Ask them what you'd like to know. You don't have a relationship with them and they aren't familiar with your version of "normal" or "mature" processes.

It doesn't matter if they're familiar with my specific concept of a mature app. (Although just reading the job description would cover 90% of it...) There's always going to be a lot of overlap of concepts anyway. The question was broad exactly because there are many good answers.

(FTR, the answers were pretty consistent in what elements they included, so it wasn't confusing for the candidates)
