Let's say I'm going to apply for a job which only need a cert/diploma for a non-executive role. I'm going to make up a story how I've been jobless for years after my diploma graduation and sometimes working as a part timer with a subcontractor as a clerk. No EPF, no pay slip... salary is paid by cash.

If they hired me, am I going to be in trouble if they found out I'm already have a bachelor/master later? Can I fought back if they fired me as there is no proof that they recorded what I said during interview?    

Currently thinking of backup plan .. 

Thank you
