The process included one round of interviews with a panel of four interviewers who took turns asking different questions. They also gave a great background into what the office does

Virtual interview with two scientists looking for a community outreach intern for sustainability. They asked few rounds of questions about how I do with scheduling, if i am ok with visiting the office, and working from home. Be prepared with questions.

Friendly, comprehensive regarding my application and resume. They actually gave me some pointers too regarding a better resume! Everyone I spoke to was incredibly friendly regarding the process, and you could tell that they really wanted to give a position to everyone that was interested in it. It's more of a graduate than undergraduate internship though, and they don't necessarily have an infrastructure in place for the undergraduate interns yet so it's more informal than formal.
