Wow, it's not that cool to just be a hater and see yourself as a 'sick' engineer that doesn't have time for PM's bull... This is actually a pretty cool exercise, and for someone like me, coming out of school and practicing algorithm interview questions (which are questionable, but hey), this is helpful and fun. Anyways, if all you want to do is say that you are cool because you're learning a functional language and are completely above java, do it in your head.
