It is unlikely that you can force the company to hire you.  Unless you already signed a contract with the employer it would be very difficult to get any damages or specific performance.  Missouri is an at-will-employment state.  This means that absent a written employment contract, you can be terminated without reason, barring a few exceptions.  You should speak with a local employment law attorney to determine if your matter fall within any of the exceptions to the rule.
