EAB's interview process requires a fairly large time commitment, especially for someone already working full-time: There was a phone screen, two in-person interviews with cases and a timed writing test that had to be scheduled and taken before the interviews.
I heard back within two weeks of my application, but was told I was being considered for a more senior position for which I was clearly unqualified. During my phone screen with the hiring manager, I brought it up, and I was thankfully switched back to the opening I had initially applied for. I also received some unsolicited constructive feedback, which was a welcome surprise.
The in-person interviews, outside of the cases, consisted mostly of behavioral questions and questions about writing and research experience. One case was more theoretical, requiring that I think of whether responsibility-centered management on some aspects would be a help or hindrance to some higher ed KPIs. The other was a program-demand case with some bare-bones quantitative data and required that I interpret trends and recommend a course of a action to a hypothetical client. The writing test was similar to the second case in structure, though without the data component.
The recruiter who initially contacted me didn't consistently respond to emails. She also sent me a report to review as preparation for a case, but it didn't come up; one of my interviewers told me that similar mistakes happen frequently.
I was told to expect to hear back within one or two weeks, but later received an apologetic email that the process would take longer as they interviewed more candidates. I received another offer in the meantime, requested an update from my recruiter (EAB was still not prepared to make a decision), and withdrew my candidacy to accept the other offer.
