Great question! You need to know their expectations and then exceed them. Just meeting all expectations is not enough because it is thought that you can easily do that, the reason you were hired. Some way to exceed in the work place is to communicate clearly, be creative, be flexible and adaptable to change, especially at short notice. Also, remain open-minded and a continuous learner. Finally, find ways to help the boss and yourself work smoother and faster, typically technology. I hope this helps with your success!
