"What's the most fulfilling project you've worked on in the last 6-12 months?" I like this because "fulfilling" means different things to different people. Some folks would deem the opportunity to work on hard technical challenges as fulfilling, whereas for some it's simply a positive impact on the customer and/or other developers (agnostic of whether the solution was simple or complex.) This also helps you gauge the quality of problems the team is working on, and how they gauge said problems. With the added dimension of time (i.e. 6-12 months) you get a sense of how recent or old are the projects that they're about to discuss. I wouldn't put much stock in something too recent (ex: something they started 2 weeks ago) but would also be suspicious if they mention projects that are 1yr+ old. More than once in my career have I run into issues when my definition of "fun/fulfilling/cool" was widely different from my boss's. Getting a heads up on this for me is critical when it comes to evaluating which team to join.
