As you are an engineering drop out student so for all practical purposes your academic qualification will be taken as class XII only. Anyway, do not take it as a retarding factor for your future career because there are numerous instances and cases in our country as well as all around the world where dropouts became the great entrepreneurs and showed their real worth to the society.
You have many options ahead and it is only the hard work and persistence of achieving your objective that matter now in bringing success and satisfying career in your life.
Your present experience is in the banking sector and what I will suggest is to go for some diploma course related to banking and commerce ( like - 1 year Diploma in Banking & Finance and 1 year Diploma in Accounting and Finance) which can give you more edge in getting a good job in financial and commercial institutions. These diplomas open scope for jobs like Credit and Risk Manager, Loan Counsellor, Investment Banker, Market Analyst, Financial Analyst, Tax Accountant, Financial Advisors, Finance Assistant & Accountant, Financial Consultant, Chief Financial Officer, Certified Public Accountant, Finance Managers etc.
The most valuable thing today you are having with you is your 5 year experience in this sector and you have now to take the mileage out of it in getting a better job in the similar line.
At this juncture do you see any possibility of completing your arrears of engineering? If so then though it is a bit late but then you can take advantage of your combined academic and experience strength to seek jobs also in big multinational companies.
Knowledge is power.
