Just do one project. Ask them for an interesting or challenging problem they had, go over it at a high level from a business and technical perspective, and then dig in as deep as you can on specific parts. Ask about business impact, how was that measured, what were the tradeoffs, what made it especially difficult, what were the alternatives, what they'd do differently, etc. If they can go deeper than you can, then that is a good sign.
