SDN, reading up on what the school is known for, talking to alumni.
What was the most difficult question?
"'Do you have any other questions or things that you want to share"-after we had already been exchanging questions back and forth for 20 minutes.
Minnesota nice. And, they let everybody know in early to mid April if they're in or not.
What impressed you negatively?
It is weird how they try hard to sell the school to everybody there, but they're only letting about half of the people in... My interviewer made commments like I was a shoo-in, but I have yet to find out.
What did you wish you had known ahead of time?
I guess everything depends on who interviews you. My professor was extremely casual, so it was all about content and not at all about presentation. He didn't even introduce himself. Be ready to talk about yourself and show excitement about the profession and the school. They want to know that you want to go there, and my interviewer wanted to learn about me with very little effort on his part.
