If you want to apply for multiple vacancies, the easiest way for you to do so is to finish your initial application and press the submit button. Then go back and apply for another position. Your application will come up and any duplicated information requested will appear. Tab through the application, change any information that you may need to, and answer questions that may not have been on the previous application. You will need to upload any supplemental materials requested once again and then submit your application.
