When you first go into the store to pick up an application, you will be invited to an impromptu interview with a manager. This is usually a department manager who you will end up working with a lot if you get the job. They'll ask standard questions based on your application (work experience, volunteer experience, education, etc.). They'll ask if you're afraid of heights and if you can climb a tall ladder and lift boxes. As much as I'd love to tell you to insist that you can regardless of your fears, this is a huge part of working at BBB (regardless of the position. Part time associates, cashiers, and district managers all get on ladders. Don't assume you can be an exception) and I've personally worked with many employees who couldn't overcome their fear of heights and became a burden to the store rather than an asset. So if you cannot, without a doubt, climb a 22' ladder, be honest and accept that his isn't the company for you.
If this first manager likes you and believes that you would be a good hire, they'll set up an interview with you and the store manager. They are the final say in your job hunt journey. They'll ask most of the same questions as the first manager. They want someone who has good people skills, can communicate effectively and efficiently, and can become a valuable employee to the store for more than a few weeks or months. BBB is a business built on teamwork, so management is not interested in someone who will jump ship as soon as they're done with training. In return, they'll train you in a large variety of tasks, help you grow to become one of the best employees anyone could ask for (make you very marketable), and support you through all of your endeavors. This is a team built store, so your team will support you.
