Is it feasible to check Date of birth validation during hiring process

Summary:

Hi Team,

I have a requirement to validate DOB filed while hiring means if an employee is below 18 years the system should throw an error message. I have checked that by using legal employer we can throw warning message but if the user clicks on yes he can be able to submit the hiring. Is it possible to create an error message if an employee age is below 18 years.

Thanks & Regards,
