No to little knowledge of Canto or Mandarin while looking for jobs in HK

I am prospective student at HKUST and would love to major in Global Business and CS and work as an Investment Banker or a Quant Trader here in Hong Kong.

The problem is that I am an international student and right now I have no knowledge of Cantonese or Mandarin. I would love to learn the languages but would it be a very big hurdle if I am unable to be proficient in them by the end of my four year study period?

My question to you guys is that can a person survive in HK with only knowing English and less of the local language in the brutal job market in Banking and Finance?

Thanks!
