Hey,
I was shortlisted for the NUS telephone interview as well...just finished the i/v this morning. There were 2 interviewers...the academic director and another lady from career services. The questions were pretty much the usual sort...why MBA, why Singapore, career aspirations and stuff. Nothing out of the way. They did ask me though on whether my career aspirations would change depending on the companies which recruit or do not recruit at NUS.

The entire interview lasted for around 16mins.
I really couldn't gauge much from their reactions...am just hoping it went well!
All the Best,
Lavender
