I applied online. The process took 3 weeks. I interviewed at George Kaiser Family Foundation (Tulsa, OK) in Mar 2019
Interview
One interview over the phone with the specific site, not with GKFF. I think there was one GKFF rep on the phone too, but the interview was focused on the site. Overall very fair and good experience.
