You don't have any rights, unfortunately. All employment, unless you already had a written employment contract, is "employment at will." Among other things, this means that the employer decides who to hire, who to promote, who to make full-time, etc. and it is 100% the employer's free choice. Not getting the job after an interview or after having worked as a "full-time temporary" employee does not give you any rights to the job or any claim to compensation.
