I had my Skype interview on the 3rd with couple of interviewers - one MBA2 & one MBA1.
I think this was unique as I haven't heard anyone having couple of interviewers in a Skype call.
MBA2 was similar in age to me I believe - between 30 & 34. I am turning 34 tomorrow..

.
Questions:
1. Resume/Past work experience
2. Why MBA now, Why MBA from US & Why Georgetown
3. Most important question around my age and the proposition of an MBA considering I will be in a class with most students in late 20s.
MBA2 told me that even he had some difficulty in convincing recruiters about his age and his target function of IB but he was successful.
I was also informed that I wouldn't be the oldest one in the class for sure
4. Interests outside of work
5. A general question around what is the biggest risk to the Financial markets at this time.
Through out the interview Skype was behaving weird and they were unable to hear me intermittently though I was able to hear them perfectly alright.
But they were fine with it.
Hope that helps others - especially older applicants.
