3 total rounds of interviews. First round was a phone screening with the hiring manager - mostly verifying that you have the skills listed in the job description plus some questions about eligibility since federal clients often require you to be a US citizen. Second round was a behavioral interview with an associate director followed by a case study that they give you 48 hours to prepare. Final interview was split into 2 behavioral interviews with a director and a partner. The behavioral interviews were pretty straightforward, but the case was definitely challenging. I highly recommend making sure you have access to Excel and prepping a Powerpoint template in advance. Before they sent me the case materials, I went through basically all the Powerpoints I've ever made and pulled a ton of slides into a template so I could spend as little time on formatting as possible.
