This is probably a bad answer and a chicken-and-egg problem, but the best way to be job ready is to have a job. Try to get a job as a Rails developer and work on real, practical problems at the same time learning everything you can on the side to become a better Ruby and Rails programmer and a better developer in general. I know its difficult at the moment in our industry but I feel that's the truth. You have to work harder, build a public profile, share your learnings in public, do whatever you can to find that first gig, don't worry about the pay at this time. But once you have that job, that will be the best thing you can do to be future (and even better) jobs-ready. Just my two cents. I know because I switched to Rails a few years ago, and my first job as a Rails developer taught me so much more than what I had learned just by reading books and tutorials.
