Student Finance Repayment

Hey everyone
so Im a graduate computer systems Network 2021,After my graduation I moved abroad and few weeks ago I returned to Uk,and I need advice on how to get a job etc website also if anyone works as technical support can help me witch cv

I have following question im concered about since then ;

What happens if you dont find a job and can not make the repayment?

what if you look for work but unable to find and on the meantime you search for work , you work as a delivery rider and dont make much, how will the repayment be ?


Thanks
