Casual. There were three interviewers in a small room and they took turns asking questions. Very nice women, somewhat intimidating but they do their best to make you feel comfortable. It was somewhat hard to find the location for the interview and street parking is difficult. There is a lot of paperwork to fill out and steps to take before they hire you. You need fingerprints, drug tests, background tests, etc. Makes sense though because you will be working with children. Overall, great company and love what they do. It would be a nice place to work, there are also many locations through out Rhode Island.
