People buy or hire people they like and your story will help them to like you.
I suggest if you are networking to get interviews or if you have an interview, practice sharing your top three qualities. Don't wait and stumble when you are asked, "tell me about yourself and why medical sales?"
Come up with specific examples that are relevant and create some emotional bonding so people are more drawn to you!
Have no doubts when the interview is over that you we were persuasive and likeable!
Practice so it flows with confidence!
