I interviewed through Skype with a 2nd year student recently.
Interview went along the lines others reported. The interviewer was casual and friendly.
Some questions:
- Walk me through your resume / tell me about your current job
- Some behavioral questions regarding leadership and teamwork
- Why business school? Why now? Why Yale?
- Questions for the interviewer (He gave very insightful and detailed answers.)
Total time was about 30 minutes, maybe a few minutes longer.
