Agreed. I try to ask kind of open questions during the interview process - I see you're doing this task with 'x' technology, have you considered using 'y'? Sometimes you'll get good responses back along the lines of why they picked the tools, but express an openness to make different choices if you can help them figure it out.

Honestly I'd love to hear ways to actually interview the interviewers on things like this. I feel most of the material I read talks about how to interview candidates, but there's not much about the other way around (how to assess the company you're interviewing with?)
