Example: I had a friend who had an interview for company XYZ, "Write a program that clicks the first link in a wikipedia entry and exits when you reach the philosophy page (implement in the language of your choice). You have 15 mins"...
My friend was a really hard working, intelligent, and honest guy and he could not do it... i doubt cheaters could do it cold.

Perhaps I am the kind of person they are trying to avoid, but I did this in a bit less than an hour. I am very ignorant of the Python library ecosystem, so if I had known the request library better and if I knew an html parsing library, I may have been able to complete this in the time limit. I also suspect there are a few cases which break my solution.

The best part is you could cap it to 5 levels of recursion before it runs away.
Still no way I'd have that in 15 minutes haha. I could describe it though!
