What do you think the job you have applied for involves?

A job description is, basically, a brief amount of information on what doing your job requires and regards, or just a subtle explanation of it. For example......A person greeter at Walmart is someone who says "Welcome to Walmart!", or gives people a friendly greeting welcoming them to the store. A cart pusher at the same store would have a different job description; Basically, a cart pusher is someone who retrieves carts from outside of the store, in the parking lot of Walmart.
