Does knowing esoteric languages help with interviewing for jobs that don't require them?
I have some knowledge (mistly forgotten) of a couple of non-mainstream languages, such as Prolog and Scheme. I definitely don't know/remember them well enough right now to pit on a resume, e.g. I would not be able to coherently answer questions from interviewer about them. However, with a bit of reading up and remembering stuff, i can fairly quickly (couple of weeks) bring myself up to the level where they would be resume-mentionable.

I will 99% likely be interviewing for positions that don't require any skill with either language (and, probably no direct skill with either functional or declarative programming.

The question is, is it a plausigble plus to invest in these couple of weeks of polishing up either of them, on the hope that having them listed will bring in extra brownie points? (e.g. interviewers would be impressed with me be flexible enough to not only know procedural/OO stuff, or would be impressed with me knowing 2 more languages than i now list)?

Or would it be a pointless waste of effort that should rather go towards working on my primary skillset improvement?

I'd like to hear the reasoning one way or another from people who do conduct technical interviews.

Thanks!
