Whether you choose to verify your credentials with Certsy or not, employers will still receive your SEEK job applications as normal. Certsy verification is 100% optional.
Verifying upfront means that Certsy can vouch for the claims you make on SEEK, for example, that you have a valid driver's licence, or the right to work in Australia. This can give employers extra confidence in shortlisting you over other candidates. However, if you do choose to verify, you always remain in control of what (if anything) you share through Certsy.
