It appears that you come in for an interview with the Site Manager and then if you are selected for a second interview, you will meet with the Clinical Supervisor. Once you wait about 3 weeks and your continued efforts to find out your standing, the position has been filled by a returning employee. So, you are then offered to interview for the same position at another site and this time you interview with the H.R. and a Clinical Supervisor and then told they are going to continue interviewing and then if you are selected, you will them interview with another Site Manager. Of course you get no offers and you just keep being interviewed.
