Are you aggressive enough in your sales role to not accept a 'no' from a potential client right away? Tell the hiring manager a bit about your method of overcoming objections.
"When I receive a technical objection on a sales call it is generally because I haven't explained that particular product feature clearly enough. I will hear the objection, repeat it back to ensure that I understand where they are coming from, and then review using simpler technical language. I will stay on that topic until the objection has been overcome."
