Although I don't know C I really like this example as it's pretty much what happens when I start a new place as a Python dev. E.g. Hey, X, we need you to change the dates on this screen to show the timezone. - Queue me then having to drill down through the codebase to find and then fix the problem etc. Only complaint would be the amount of time it may require to do in an interview.
