I am developing a web portal which will store the job requirement like, experience, salary etc in a database and whenever any user (new/old) matches that criteria the job should display him in his dashboard after he logins.
My Columns in employees are
Age, City, Industry, Marital status.

So, when admin post the jobs, he will define the criteria which user can see this. For ex. Age between 20-30, City only Mumbai like that.

How do I store these information in database efficiently.

I am using PHP/MySQL.
