For a Phoenix application, a Ruby on Rails developer will be able to pick it up pretty fast. Usually just takes one or two pair programming sessions going through the full MVC flow with test-driven development and they're good to take on most tasks. Then reading up some of the official Getting Started Elixir docs fills in the gaps, particularly understanding how a Process[0] works, working up to Tasks/GenServers/Supervisors under the Mix and OTP section.
For hires that already know Elixir, I've found the talent pool to be way above the average (and expensive). They're usually senior devs that fell in love with Elixir, wanting to move away from their previous tech stacks or have already worked at an Elixir shop.
