I applied online. The process took 2 months. I interviewed at The Poynter Institute (Saint Petersburg, FL) in Mar 2022
Interview
First was an HR screening Then a round of Zoom interviews Finalists for top positions flown to meet in-person; others are hired remotely. You will generally meet a lot of people. It's a small nonprofit so people expect to meet a variety of people in the finalists levels.
Interview questions [1]
Question 1
As others have said, these are pretty smart folks who ask good questions. A lot depends on the role but be prepared to know a lot about current events, mis- and disinformation, journalism ethics, etc. (You are applying at a journalism institute so it should come pretty naturally)
