Is it permissible for a woman to post her picture wearing the legal hijab on recruitment websites if the purpose of that is to prove the account belongs to a real person and to increase interest in the job application?

It is not permissible for a woman to post her picture with an uncovered face, allowing foreign men to see it on the internet or social media sites, unless there is a need for it. For instance, if a woman needs to work and verify her identity, and the website is trustworthy, then there is no objection in such a case, especially since some scholars hold the view that a woman's face is not awrah (private parts that must be covered).
