Background: 4 years as a statistical analyst for a consulting firm in the process industry
I interviewed with a first year at Wharton, extremely nice guy. The interview was really laid back. I just did it walking around in my apartment and treated it like a regular conversation with a friend (that helped me get more comfortable). I printed out my resume and the essay portion of my application but I actually did not use it at all. I am not sure if the person interviewing you has seen your application, I didn't get a sense either way. He didn't ask me anything specific to my application. I wrote down bullet points to answer questions, "why mlt?", "why an mba?", "why now?" etc. I didn't write down full answers because I didn't want to sound too rehearsed. The only negative about that is that my answers weren't as smooth as they could have been, but it might have helped me sound authentic. A few questions I got that others might also get:
Give an example of when you have been "scrappy"?
What is your leadership style?
What are you willing to sacrifice to be successful during MLT?
I bombed the last two questions in my opinion, my answers were terrible lol. I did ask him a lot of questions and that might have helped. I asked a bunch of questions covering various topics, like:
Pre-MBA internships
First year internships
Hardest part of MLT
Biggest thing he gained from MLT
How he picked his school
Business school experience
Post-MBA plans
To be honest, I didn't think my interview went great but I didn't think it was the worst either. I felt okay after. I sent a thank you email afterwards. Hope this helps, feel free to contact me if you have any other questions. Good luck and I look forward to meeting everyone.
