Internship dilema

Hi all, I'm new to WSO and after looking through tons of articles and forum posts, I've decided to join the community.

I am currently studying in a business school and I am 2 years away from graduation. I have a question that I would like to ask. Any replies would mean alot to me.

Some background to the question, I have decided to work in TAS services once I graduate. However that would be in 2 years time. I have secured an internship in TAS for the coming christmas break., i was wondering what would be the best way to attain a return offer from this same company offering me the chance to intern there.

Should i just continue to intern there till i graduate, in which I would be able to attain approximately 6 months of work experience there or search for other opportunities which might present themselves? Such as going to BB or other financial institutions.

Thanks in advance.
