AMMATOLI mediterranean bites interview questions

I came in and asked for the manager. The manager then gave me an application to fill out. I wasn't finish filling out the application when he came to have a look at it. He told me the pay, what days would he need me and what my duties were. I was offered the position and was told that I would be contacted again on when to start. A week has passed and I followed up with an email. I was told they weren't hiring yet have a now hiring posted on here. Very unprofessional and dishonest. He did give off a bad vibe as he wasn't even smiling at all and seemed so serious. Disappointing experience.
