Question, perhaps an odd one:
Had my interview yesterday, think it went reasonably well. However, when we reached the subject of my volunteer experience...I have a hard time talking about it without getting emotional. I work with a children's bereavement camp that I attended after my father died over 10 years ago; I've been volunteering with them since I was 17, and its something that is extremely close to my heart because of the children I've met and the stories I've come into contact with there. This is the second interview that I have actually teared up/gotten pretty emotional while talking about my involvement with this organization, though I believe I managed to answer the question thoroughly/articulately despite crying (still makes me cringe). This happened during my McCombs interview as well, and I was admitted there with a full ride, so clearly they appreciated the "extra sincerity" I guess.
My question is, do you think this hurts my chances at Kellogg at all, or do you think they will see it as a sign of my genuine passion for and commitment to the organization?
Thanks...every time I think about it, I die a little inside

I'm certainly not an expert, but as long as you weren't straight-up sobbing / unable to carry on, I can't imagine this would count against you. Especially at Kellogg where they seem a little more "human" than some other Ad Comms. I would guess this felt like a bigger deal to you than it did to the interviewer. Any reasonably empathetic person would understand why it's an emotional subject for you. And it does show sincere dedication to your cause. Did your interviewer react in the moment in any way?
