Thanks for sharing this. It took me less than an hour to complete and I thought it was pretty fun. These sort of interview challenges that involve rapidly diving into a foreign codebase are really great, but it has to be done correctly. I once frustratingly & embarrassingly failed a live coding interview where I was asked to fix some sort of linked list issue in a fairly large C code base that wouldn't compile. I much prefer a challenge that involves implementing a new feature in a working code base (like this memcached question) as it's closer to reality and will also provide a better experience for the candidate.
