I had a project give me a take home exam with a link to the git repo and basic instructions on implementing a simple algorithm, as well as tests, and FFI bindings. That took a couple hours, then I had two 1-hour remote interviews discussing the code. I thought the process was pretty good: even though I was annoyed at having to do the take-home bit, it served to demonstrate that I could navigate the project source code, build files, learn the FFI interface, etc. The algorithm itself was fairly simple to implement with a little thought, although they probably didn't care if I looked up how to solve the problem on Wikipedia. Personally I think that being able to figure out where the tests were, how to add FFI, etc., was one of their biggest requirements. Anyway, I thought it was robust but not too time-consuming interview process. I think such an interview could use a reasonably-sized open source project for this, instead of their internal code base.
