R2 interview decision are scheduled to be sent out on February 10th but if they do the same they will actually be sent out on the evening of February 9th, perhaps to ensure that applicants from Asia get the decision on the 10th. A few days later, you will get the contact info of an LBS alumni in your location and can set up an interview.
Overall, I found the interviews very relaxed and informal. I heard it depends very much on your interviewer though. In my case, I talked to some LBS students and alumni I knew and asked them for advice, but everybody just said relax, be yourself and know why you want to do an MBA and why you want to go to LBS. Also they told me to read through my application essays again. I also checked the MBA interview advice on accepted.com that I found very helpful. I didn't know back then (maybe the page didn't exist then) but clear admit's MBA admissions wiki is also extremely helpful.
They matched me with a very recent alumni (MBA2005) who worked in my city. Because I'm out of town during weekdays and he was traveling as well, we agreed to hold it on a Saturday. Saturday came and I had tonsilitis and my interviewer called that he actually had the flu, so we just agreed to do it the next day. So as I said, pretty flexible and informal.
The way it seems to work is that LBS sends out a list of dozens of questions to the interviewers separated into several categories. So each interviewer would get 10 questions on "motivation", 10 questions on "leadership", 10 questions on "team work" and so on. And then I think the interviewer picks the questions he wants to ask out of that list and also adds some of his own questions that he had while looking through your application (at least this is what I gathered from watching him during the interview).
Typical questions would be
- "Have you ever lead a team?"
- "Did you ever face a problem with a client? How did you handle it?"
- "What do you want to do after the MBA?"
- "Since you also applied to other schools, how will you decide which school to go to?"
Then I asked some more questions about things I wanted to know more about, like shadowing and summer internships and the exchange. He was very helpful and in the end we talked for almost 3 hours. I don't know how you could fit all those questions in an hour, since the interview is supposed to take about an hour, but I think in general it is more likely to last two hours.
For those of you who are invited to interviews on February 10th, feel free to post more questions and good luck!
