I remember the best interview I had was at a company offering open source software. For the coding components of the interview they give applicants a task (they cherry pick one of the easier ones) from their JIRA backlog and told applicants they've got two weeks to come up with a patch. It didn't matter if the applicant could fully solve the bug/feature, since it's not particularly fair to expect the applicant to be familiar with the ins and outs and gotchas of the system they are working with, but what did matter is that they A) submitted something, and B) could talk their way through their thought process and how they arrived at their current solution.
This sort of process really clicked with me. Obviously it's not as straightforward for some organisations that may offer proprietary software, but the process could certainly be adapted for a lot of organisations, in my opinion.
