Amir,
We feature community member profiles in Tamil Wikipedia homepage and Wikimedia India chapter archives. It gives a brief intro about their background and links to their significant Wikimedia related contributions.

Wikimedia India acrhive for 2015 - http://wiki.wikimedia.in/Featured_Wikimedian/Archive/2015
We do not interview but let them write these short profiles. There is also a nomination process. While only more seasoned contributors are featured this way, it is definitely a motivation for newcomers to contribute more.
Whenever there is a community gathering, we also try to create video interviews.
