Yes, this is not uncommon because the four other recruiters all want your business. If one of them finds you a job before the others, that one will get the commission for getting you the job. Recruiters have to find a certain amount of people jobs per day or they will lose their own job. Someone I know that became a recruiter said that they had to be on the phone a certain amount of minutes during the course of a day or they would lose their job. They would also have to find a certain amount of people a job per day or again they would lose their job. Being a recruiter can be a tough business.
