Here is when I know/remember:
They did one day of interviews in DC, and we were told they were interviewing 40 people. It was optional to sign up. The interviews took place at Jones Day in DC. They had like 5 or 6 Indiana Law alums doing the interviews, they all worked for Jones Day or the government, in some context. They were individual interviews, some people were interviewed by 2 alums, I just had one. It was really short- 20 minutes. My interviewer was really chatty but sort of awkward... I felt like I could barely get a word in. I was literally asked 3 questions (why law school? to what other schools did you apply? what type of law are you interested in?), then he took a glance at my resume, and started talking about my hometown, since he'd been there. He talked for a long time, then asked me if I had any questions. Then he gave some long-winded answers to my questions, then I was on my way. Overall the process was was pretty friendly and non-intimidating. My interviewer seemed like a really nice guy, but I also feel a little bothered that this one individual has a potentially large say in whether or not I'm admitted, when all we did was sit in a room together for 20 minutes, and he talked for at least 10 of them.
I was also sort of confused that the "why Indiana" question was not asked. Shouldn't that be a given? I had a great answer ready, and when it became obvious that he wasn't going to ask it, I'd tried to work it in anyways. But still... strange.
