it can vary like crazy, for all sorts of reasons, or it might be you wont get called. the only way to know for sure is if you find out someone in your group got hired, or something like that. they will postpone a class on short notice, all sorts of stuff. dont put your life on hold, but hope for the best. also, if you dont get hired, dont give up. it can take quite a few tries sometimes. if you dont make it this time, dont think its the end. keep trying ,and put in for any posted job.you never know what they wuill hire you for.
