Sometimes you don't know what you don't know. I was completely torn apart the first time I was interviewed for a Scala position, because the guy didn't believe I could possibly have spent three months doing Scala professionally and didn't know basic List methods like fold (we'd been avoiding using Scala collections because we knew the migration was coming, and had just been writing Scala with the Java collections).

My first scala job was with a group that didn't like to use a lot of the more FP-like constructs such as folding. So I also didn't have experience with that after three months. You could argue that meant I wasn't really using scala but I wasn't totally clueless.
