Hello!
I've never been to University of Ottawa or New Zealand, but I am a current student at Hult and hopefully I can offer some insight.
Hult's international community is #1 in the world. The perspectives and viewpoints you'll encounter here are unparalleled. There is a lot of hands on work and projects. Classroom stuff is relevant and applicable. I'm about 7 months into my studies and I feel a lot more prepared to succeed in a real-life job now. The professors are successful business people too - not just PhDs discussion academia stuff. Its really great having everything done in one year as well, quicker to jumpstart your career.
And by the end of it, you'll have connections and friends all over the world - an invaluable asset.
Best of luck!
