Good luck R1 applicants!! R2 here and had both my interviews last week. Some interesting questions that I hadn't come across with LBS nor in any of my interview prep sessions with my MBA friends. Both interviewers asked me:
1. Looking at your resume right now, you could make the transition to MBB. Why don't you do it?
2. You will be significantly underaged at Insead, how do you expect to compete with your peers who have more experience?
Other questions were generally quite straight forward.
