Teach for America interview questions

I met TFA recruiters at my school's job fair. I was/am interested in education, so I spoke to them and gave them my resume. Very late in the year, I got an email from someone at TFA asking if I was still interested in working here for the summer. First, I had a phone interview with someone from HA (human assets), then I had a phone interview with the people on the team that I would be working with. All the interviewing was done in about a week. My perceptions of the people-- the people here are great. My perception of the office is a little different. There's a lot of great people, but the organization is very much divided into silos. Different departments, and even different teams within departments, do not interact very much.
