Phone / Skype interview (I applied to 2 different locations) then for 2nd in-person interview, there were 3 people sitting across from me taking turns asking questions, one person had been a health educator the previous year.

The interview was pretty chill. Asked typical interview questions (strengths, weaknesses, why I am interested in Americorps). there are 3 rounds to the interviewing process. The first is written, then you have an in-person interview, if you make it past that round there is a third interview with the host site of choice.
