Hey guys,
I'm still licking my wounds from my HBS interview in November (got a ding if you couldn't tell), but thought I'd share my advice. Take it for what it's worth.
I recommend spending at least 75% of your prep on interviewing techniques (e.g., poise, taking time to think through your answers before speaking, remaining calm). I am in consulting and regularly lead meetings with client executives so I felt pretty comfortable in this area and focused most of my attention to prepping for various questions. I even did a mock with Sandy in which he praised my poise and communication style (BTW, I recommend Sandy)...
All that went out the window in Dillon House...I turned into a babbling idiot as if I had never talked to anyone in my life. Oh, and I only got one question that was even remotely similar to any questions I had prepped for.
Long story short, don't worry about the questions, you'll know all the answers. Just make sure you're able to convey them without sounding like an idiot
Good luck!
