So my first thought was the same thing, and so I started thinking "What would I say"? And while I started with "Hmm, I don't really remember hard bugs; I remember times I spent days, and the lessons I took away, such as the importance sometimes of putting a problem down and sleeping on it...I guess this one time when I had to figure out why something was so slow and eventually tracked it down to an O(n^2) implementation when it could have been linear was cool...oh, but wait, we actually had something here where due to mutable state we were growing a list without end and it was being sent out across the network, and we hadn't tested it in staging because it was just for metrics, and that ended up taking out a downstream system in prod" and...well, I found some stuff. I think if asked something interesting, at least, will come to mind before too long.
