A similar recent question made me think about a situation I overheard recently.
A developer/DevOps friend of mine who has an easy-headed attitude to everything, often comes up with little quirks. One time he mentioned it would be an interesting twist for his future job endeavors if he modifies his CV in a way that the programming skill of using regular expressions is stated as speaking a foreign language.
He based this on the premise that regex is hard and outlandish, and that if someone asks about it in an interview, that's a good way to discuss about it light-heartedly and thus to become more appealing during the process.
However, in my book it is unprofessional. What is a more general stance on matters like this?
