It was with an alum who works at a large corporation close to where I live. I'll probably write a more detailed blog entry latter on, but the gist of it is
1. Very friendly and cordial (right from e-mail communication to actual meeting)
2. Enthusiastic about what INSEAD did for him. He felt that the year spent was the best year of his life - very intense but rewarding.
3. We had a good conversation, mostly informal, including usual questions like "why MBA? why INSEAD" etc. I know quite precisely why and why INSEAD so I think my answers were reasonably clear. Some of my points resonated with him. He tone was also "when you are in INSEAD you will face this.. that ... etc.", the usage of "you in INSEAD" is a little more positive than a totally neutral tone.
4. He spoke quite a lot about his experience and the opportunities he got later on. It was good to listen to, and re-inforced my interest.
Finally, it's not all over until it's over. At least this was a good step forward.
Anyone else did their interview?
