I started with Rails at 4.x, and having never written a line of Ruby prior it took me about two weeks to be fluent enough to handle most anything thrown at me in the course of "typical" webapp development. That was about a year ago, and these days my biggest challenge is identifying and filling knowledge gaps. For instance: the mere fact that ActiveJob exists isn't obvious.
