Hello!
You should not be worried about yuor profile not being 100% business, if you got the interview is because they find it interesting. However, don´t commit the mistake of thinking that this is going to make it somehow "easier" or more "merciful" if you make a mistake, for the fact that you have not worked in business before.
The bar is the same for all candidates, regardless of the background, and it´s always very high.
It´s totally normal to be nervous even if you feel you are well prepared, so don´t worry and just make the most out of the time you have left to polish whatever you are struggeling most with.
Good luck!
Cheers,
Clara
