I have a job interview for a trainee financial advisor this week. Any advice?

I've worked in retail management and at a bank doing trusts/pre loans for mortgages and financial support etc.

I've been sharpening up my knowledge on pensions and ISA's, and will accustom myself with the company.

Is there anything else I can do to really impress in the interview. This would be a perfect position for me. I'm 25m.

Thanks!
