Ms Valkó started her professional career at Arthur Andersen. She soon gained the British and a couple of years later the Hungarian chartered accountancy qualification. She worked for Arthur Andersen in Budapest and London, and was the finance director of a Dutch off-shore entity. Later, Ms Valkó became a project manager in MOL's Accounting and Tax department, in charge of the day-to-day cooperation with the accounting service provider, employing 250 employees.
Ms Valkó spends her free time almost entirely with her two children. She also does a lot of reading and finds great pleasure in a quiet evening in with a good book. She also runs a couple of times a week. She believes that it does not only refresh the body, but the mind too.
