I had three interviews, on three different days with a different manager or pair of managers each time, wherein I discussed my relevant experience, my life and ambitions, my expectations and theirs, etc. If I had to wait, I was offered a refreshment, then advised as to how long the wait might be. The interviews themselves were structured, and they asked me questions from what looked to be a set list, taking notes with every response, but I was made to feel very at ease also, and the conversations were friendly. Although it's never particularly fun to sit across a table from someone while they judge you, the fact that that was, in essence, what was happening was not magnified, and the overall experience was pleasant. They also do, if I remember correctly, have an online test that they use for purposes of pre-screening candidates. When I took it, it was primarily (if not all) multiple choice and consisted of hypothetical questions that seemed to be geared toward gauging one's sense of ethics, approach to time management, decision-making, etc. I actually had applied some years prior and never made it past the pre-screening test, which I think is funny. Draw your own conclusions. :)
