Confident means having strong belief or full assurance. That is it is having no uncertainty about one's own abilities, correctness, successfulness, etc
Over confidence means too confident, cocksure. However, sometimes over confidence of a person speaks of his arrogance and recklessness inviting troubles.
However, when you perform a job well without interruptions, you know that you are confident.
