What happens at a Chapter 13 Bankruptcy hearing? We're in GA?

My wife and I are filing chapter 13 bankruptcy. Our lawyer told us today that we would have to go to 2 hearings in court once we sign the papers for the bankruptcy. What exactly happens at these hearings? Are we going to get bombarded with questions by lawyers from the creditors? Is it a fairly smooth process I mean once we sign the papers the trustee has approved the repayment plan right?
