There were three rounds, increasing in difficulty for each round. Started out with current ambassadors, then with the coordinators of the program, then the dean of admissions. The current seniors were helpful in answering questions. Its all to sell the school, so they asked a lot about why I should be the one who gets to do that rather than the other 50 applicants.

Very competitive position. Fair selection. 3 rounds: 1st round decisions based on application questions. 2nd round based on current-ambassador interview (3 interviewers). 3rd round based on staff interviews. Overall a great experience.
