I was contacted by a recruiter via LinkedIn who told me about the position. I applied and received an email about flying out to D.C. for an interview the following week. The whole interview process took about 3 hours (two interviews in one day). The majority of the questions in the first interview were behavioral questions. The second interview was a case study where I had to explain what I would do in a hypothetical situation. The interviews were challenging, but doable as long as you take the time to study the information they provide and prepare answers ahead of time. The entire process from application to offer letter took about three weeks.
