Absolutely! Our new system allows multiple document attachments and resume versions for Job Seekers to add on their profiles. We recommend keeping it simple with the initial application requirements (resume, cover letter, photo), then requesting additional files from candidates you choose to work with.
There is also a great screening section at the end of the job posting form that allows you to ask specific questions and get detailed responses with each application. Many employers find this useful for pre-qualifying applicants. Again, keep it simple with yes/no questions and only short answers required.
