As a sales representative, your ability to speak to clients has a large impact on the company’s profits. Great interpersonal, listening, and marketing skills are all essential. As sales reps often encounter skeptical or difficult customers, employers will be looking to assess your ability to present a product with ease, counter objections, and bounce back from rejection. Be prepared to give a convincing sales pitch on one of the company's products or role-play a situation in which you have to persuade difficult customer.
The dreaded tell me about yourself question
I was not completely prepared for this question. I rambled about me being in college and other things but I now know that the answer should never be personal and should always relate to your experience and the position your are interviewing for.
