"Employers are looking to hire cashiers with great customer service skills and experience handling cash. In preparation for an interview, come ready to answer role-play questions that will assess your ability to appease difficult customers under stressful circumstances. Make sure to showcase a positive and easy-to-work-with attitude that will convince your interviewer you're right for the job."
The most difficult question for me was "What are your three weaknesses?" but they also asked "What are your favorite products from whole foods?"
Don't say food if you do be very specific of what food. Be positive and research the company. Sell yourself. Of all of the people who are competing against you for the job why should you be picked. Even if you don't have much experience, turn that into something positive. Whatever you say that can be negative, bring a positive aspect to it. Don't try to work here if you won't be enthusiastic about what this company stands for.
