I applied online. The process took 3 weeks. I interviewed at Environmental Defense Fund
Interview
Great experience. I had one interview where they asked why I was interested in EDF and more specific questions about my experiences (and how they would aid me in an internship). I also had questions prepared for my interviewer.
Two employees interviewed me through Zoom. It was very laid back. They asked questions about experiences on my resume and wanted to get to know me. It didn't feel like an average interview.
