"When hiring sales associates, employers are looking for charismatic candidates who can provide helpful advice to customers and close sales. Be prepared to answer a few scenario questions that will assess your ability to handle difficult customers, sell a product, or excel on a team. Previous sales experience is an advantage, but not necessary."
How would you deal with difficult customer?
I would do my best to figure out exactly what it is that they need and if Im unable to accommodate them, call a manager to either figure out how to solve the problem or explain why we're unable to help.
