Initially emailed with an HR assistant and had a brief phone interview with her. I was invited to do an in person interview which lasted from 9am-3pm. During this time, I provided a writing sample and spoke with 2 project managers. Each one spent about 30 minutes on a behavioral interview with fairly straightforward questions. There was also a case interview which asked you to explain how you would conduct research to answer a specific question for a company.

Process moved very quickly. Was contacted for a phone interview about a week after applying online. Phone interview was strictly fit--with a career management representatives and lasted 20-30 minutes. Questions such as "why ABC?" as well as basic questions about resume, strengths, weaknesses, etc. Was told same day that I would be flown out to the DC office. Arranged an in-person interview for the following week. They paid for hotel and airfare. In-person interview consisted of a writing test and three one-and-one's. Two were simple case interviews and one was strictly fit. Everyone was extremely friendly and welcoming. Company is big on culture.
