Have you been a supervisor or lead before? If so, that's great! Simply share where you worked, your job title, a brief overview of your day-to-day duties, and something you liked about each leadership role.
If you haven't been a supervisor or lead before, no problem! Just think outside the box! Have you coached a little league team? Have you been a math tutor? Did you lead a project in your last job? Were you assigned to run a new process? Or, maybe you are the leader of a boy scout troop! Simply share where you have led a group of people including your usual responsibilities. Be sure to mention that you enjoyed the experience, and you look forward to translating your experiences into the Warehouse Supervisor job.
