Approach it like a sales meeting

If you’re a good sales person, you should be able to sell yourself. Think about it from the company’s point of view – if you’re not able to sell yourself, how are you going to sell their product? You’ll also be representing them in the marketplace so bear this in mind throughout the interview.

One thing to bear in mind is that you should definitely look to be consultative rather than “salesy”. More than ever, businesses are looking for sales people who offer solutions to their clients’ problems. Few now go for an aggressive old-school sales approach.

Have a list of questions ready

When the interview is coming to a close and you’re asked if you have any questions, don’t just say “no”. Thoughtful questions indicate to the interviewer two things:
1) your interest in the company and the role
2) your ability to listen to what you’ve been told during the interview (they’re not going to want to hire a sales person who only talks about the product they’re selling and doesn’t listen to what they’re being told).
