Open Question: How can I tell if I've been hired or not?

Ok I had a job interview yesterday at a Family Restaurant where I live and I was talking to the guy that was interviewing me for the positions that he had open and he said he needs someone to work the salad and hot buffet bars. He also stated that he would like to try and get me on the schedule there as soon as this Monday and if I don't hear from him by Monday I should give him a call back. Does this sound like I have the job or not? I NEED TO KNOW ASAP!
