I first interviewed over the phone with the department manager. This was followed by a second roundtable discussion with 4 members of senior staff, each taking turns to ask questions one by one. It was an intimidating setup but overall the interview felt conversational.
Half hour phone call followed by in-person interview with a roundtable of three staff members, where I fielded questions from each person and engaged in a group dialogue about my qualifications, knowledge of the organization, and career goals
