i have an interview on Monday

This was the advertisement
Busy Glasgow City Centre office is looking to fill full time sales assistant positions as soon as possible.

Due to client demand we are expanding in the New Year and so we need take on board a new generation of sales assistants to join our established teams.

If you are interested in such a position then please e-mail us a copy of your CV. Those who are to be considered for the first stage of interviews will be contacted within 3 working days.

We welcome candidates with no sales experience as we provide all training.

I have no previous Sales experience so i was wondering if anyone had any tips to make myself seem like the right candidate to employment. I have a background in music business and have experience in promotion of artists etc.
Cheers, could anyone else suggest what sort of questions they will be asking as well?
