Have you participated in Open-Source projects? There is leadership: a few (2-3) the most active contributors. The thing is it's easier to find them if the project is Open-Source. And contributors can make sure in advance they like the project. E.g. I started contributing to someone else's project with lots of stars on GH. And after some period of time became its maintainer and the second leader. If I had to go through interviews first and all that stuff that hiring requires, I would never be there.
