How do I justify 3-5 years of gap after graduation in a bank PO interview without any work experience and just doing preparation?

You can also say my financial condition is week so for my daily expenses and study i used to give private tution and in between i become a bit money addicted like Rs 10–12 thousand was very much

Just simply say that I was preparing but I failed.

This time I have passed so I am here in front of you with a hope of being employed this year…..

You can also say my financial condition is week so for my daily expenses and study i used to give private tution and in between i become a bit money addicted like Rs 10–12 thousand was very much so i focused a bit low on my exams then i realised and bounce back in my preparation.
