I would like to challenge myself with The Gilded Rose Problem. For the ones unfamiliar with this popular interview assignment, Brad Cypert gives some tips and a general introduction a in one of his blog posts. You can find it here.
In general, it is a problem about refactoring where you should meet some requirements by implementing additional functionalities by operating on a piece of (crappy) legacy code.
This challenge can be taken in most of the popular languages and I think that the combination between language and IDE (for refactoring purposes) is crucial to differentiate a great solution from an OK one. I was thinking about combining IntelliJ, since I have experience with it and I think it is great for refactoring and Java, since it is one of the language I am more comfortable with. However, any other recommendation is more than welcomed and I will be happy to try and experiment with new languages and tools.
Lastly, I was wondering whether someone could provide any guidelines or a more detailed tip based on past experiences about this problem.
