"As a management trainee, your ultimate goal is to become a manager through your ability to analyze, organize, and collaborate. In an interview context, employers will be interested to see if you are familiar with how they operate, what your motivation is, and the meaning of customer service to you. Often times, you will be responsible for handling difficult customers, so know how you would role-play this scenario. To show that you are up for this job, emphasize that you are up for challenges, multi-tasking, and leadership."
