What is the ruling on removing the hijab for a few minutes during a job interview, under circumstances of extreme necessity to secure a livelihood for a child, and does this affect previous rewards or the blessing in provision?

A woman is permitted to remove her hijab in front of the recruitment officer when signing the contract if she is compelled to work due to the absence of a provider and cannot find another job that meets her needs. This is especially true if the intention is to reveal the face and hands, as Islamic law has allowed her to do so in cases of necessity.
