I can definitely speak to that last sentence. I recently quit my job for various reasons, and way too many responsibilities for a 2 person team was one of them. We had enough work for 6 people, and things were always on fire because we weren't allowed to make infrastructure maintenance a higher priority than shipping the product -- it was excruciating!
Now when I am interviewing, and explaining the breadth of my previous responsibilities, instead of whining about it ("ugh I was sooo overworked") I use it to my advantage ("It was challenging, but I learned a lot, and now I feel I'm better at managing my time/planning skills as a result")
