Online recruitment asked me for photos, is it credible?

It is normal to ask for photos for the following reasons:

First of all, you need photos in the recruitment direction. They want to know more about you, so they want to have a general understanding of you through your photos.

In addition, recruiters need your photos to make work permits and employee files. This is the preparatory work that the recruiter should do well before the job seeker joins the job.

So they want your picture. This is also a matter of reason.
