GDPR: how to obtain candidate consent (France)

Summary:

hi everyone, I'm looking for suggestions, best pratices in order to obtain candidate consent for all external candidates who apply to a job

Content (required):

Functionnality called Request Additional Details is not appropriate because the consent must be given just before the candidate apply.

I would like to add a check box at the end of the job application flow to review and consent to our privacy policy, and in this case consent is stored in candidate profil and recruiters can view consent status

could you please let me know if it is possible, and so how to do it? if not thanks for your suggestions
