When I interviewed with Toptal, once I made it through the preliminary screenings, the final test was to build a simple web application over the course of 2-3 days in a language of my choice, and commit the code to their git repository, and demo it live.

I finished it in a day and a half; decided to use Meteor since I never used it before and figured it'd be a good time to dabble in it.

It was by far the most enjoyable part of the application process. And I think its the best indication of a developer's ability. Real-word application of the knowledge that you will probably be using 90% of the time (as opposed to theory and logic puzzles).
