I don't know if this is obvious, or if it applies to all kinds of jobs. Something I do is give all candidates an assignment: here is a problem, solve it, and let's discuss it over Skype/Webex/etc.

The best solution typically wins. There is no way to fake talent when an actual job-related problem needs to be solved and then a solution sold to a team of folks.

There are issues with this approach too: somebody else could help the candidate, the presentation style, etc. Picking the right problem to solve is important, as is deciding ahead of time what is the criteria for selection.
