I like this internship because it has given me real world experience in how to apply my mathematics degree to a business oriented field.
What I wish was different
I wish I was able to do more math related tasks in my internship. However, I chose to do a more business-oriented internship rather than analysis-oriented.
Advice
It is very important to work quickly while still being efficient. Do something for the company that helps them in a way they would not have done without you. If you can make yourself valuable and irreplaceable to the company, they will keep you around.
