If I have an uploaded resume in JobStreet, do I still need to fill in the position and roles using their resume function? Whenever I click 'Apply Now', it prompts me a dialogue asking me to fill in the position and roles but I choose to skip and continue. Also, I know it's recommended but is it okay to leave nothing for the 'Make your pitch!' box?

Edited: When I submit the application, is the uploaded resume already submitted together along?
