Well sorry to be crude, but it just signals that you&#x27;re all talk. You say you&#x27;re a great programmer, and could learn to program in Ruby in a few days, yet in 10 years you&#x27;ve never done it, even though you are apparently applying for jobs that are interested in that skill.<p>If you can&#x27;t even bother with learning the language that&#x27;s requested in the advert in a few days, why should a hiring manager be interested in you?<p>I&#x27;m also in my late twenties, and have been programming for money for over 10 years and I also like to brag about how I&#x27;m a great programmer and am fluent in over a dozen programming languages, but you bet that if I&#x27;d go for a job that requests Node.JS experience (I wouldn&#x27;t), I&#x27;d brush up on my Node.JS and make sure my resume lists it as a core competency. You can&#x27;t just go around saying you&#x27;re a great programmer and expect people to believe it from ten years of Java experience.
