It was fine. I was asked about academic interests. Then I was flown to DC to interview. This was years ago, though, I don't know how applicable this is anymore.
Three rounds of interviews as well as a written "take home" case study test. They were very communicative and gave clear directions. The writing portion has a quick turnaround time (keep an eye out so you don't miss it!).

Question 1
How would you work with a client that has different views from your own?
Smooth process with detailed instructions and clear structure. Interviewers were approachable and clear, but sometimes lacked direction. All interviews were conducted over Zoom which made the process somewhat easier to navigate.
