Hi,
I got the invite and I decided to call them.
The lady I spoke with said they are looking for graduate interns who have interest in starting their own business. It's a paid internship and you would be able to learn how to do your business while working for/with them. I didn't ask how much the pay would be tho, I guess I would find out tomorrow.
I would suggest you call the number on Dortan website for more clarification.
