Whole day, many interview panels but everyone was super friendly and there was not a lot of tough questions asked. They will ask about your research. They are concerned with quantitative experience.

The first interview was a 30-minute phone call with the recruiter. The second round included a one-day onsite visit to Arlington, VA. It was a busy day, including seven interviews with division and program leaders and a 40-minute presentation, followed by a social with more of the team members at a restaurant/bar down the street. I expected the day to be very draining, but the team members were all super welcoming and encouraging. It felt like a very supportive environment and though I didn't know much about the company before the visit, I fell in love with the culture and people during the day-long visit.
