I did not schedule an interview as I applied Round 5 at the last moment and didn't notice the April 20th deadline for interviews until it was too late. Last week, I got a call from Dylan Stafford asking if he could just speak with me for 15-20 mins. He said interviews were not mandatory but he wanted to talk and find out more about me. I don't know if this information is helpful, but that was my experience.
Also, I called to confirm about Fellowships and they are not offered for first year FEMBA students, but they said if funds are available they will send out applications to first year FEMBA students to receive scholarship money, but it was not a lot of money from what they told me.
