A job can have multiple positions available. If the job is for multiple cities/locations, but no more than 2-5 depending on the selected recruitment service, the number of positions cannot be lower than the number of locations. Each job posting must be for a single role (e.g., Sales Associate or Accountant), as responsibilities and career levels differ. The job title cannot be changed after publication (e.g., you cannot change Sales Assistant to Purchasing Manager). Altering the job title would create confusion and errors for the targeted candidates.
