Can I get a job in GS, JPM, ML ect???????????

Hallo..I am Polish. I did 2.5 years of education in economics field at the polish university. After that i did double degree: BBA from polish top business school and NLU in Chicago. I also recived MPhil in Economics from polish finance academy and Msc in International Finance and Business Economics from Erasmus School of economics which is a top european economics school. I studied as an exchange student in Russia, Spain and India. I speak Polish, English, Russian, Spanish and German. My gpa from undergraduate studies is low, 3.0:( but I improved it by doing advanced degree; gpa 3.8. My internships: - part-time job as a Sales and Marketing Manager, Night Club. - 18 months Hotel Management internship (Top UK 25 restaurants), Jr Manager. - 2 summer interships (Top Country House Hotel in the world,UK), Restaurant and Bars Supervisor. - 1 summer internship (Citi Bank). - 1 summer internship (P&G, sales). - personal experience in trading equities listed on Warsaw Stock Exchange.

I am 28 years old. I would like to get a job in SALES, Ibanking in London. Do I have a chance???????? Normaly people in Poland graduate with Master degree when they 24-25 years old. I lost 2.5 years doing economics at the poor university:( but I didn't have money for better Business School.

Thank you for advice.
