Metallicwings, I reckon you are more likely to be the 50th candidate. I think 08/04/04 represents the date i.e. 4th april 2008, maybe that is when the application process was opened? Did you apply early?
Or maybe you are the 50th person who applied for a job on that particular date? My own application is down in the 400's (or 4400's),
