NWR - School Interviews

So I have an upcoming interview for a public school social work position. For those of you who have experienced a public school interview (either teaching or other position), would you have any info for me on what to expect? It is such a great opportunity and I want to be prepared. I have heard that usually there are call backs if they like you and also interviews with a board of people. Any help would be appreciated !

TIA !!! Wish me luck !
