I wonder if you have found anything. My son is thinking about an internship in the Ukraine so I've visited that Employment Fair today and talked to a few companies like KPMG and OTP Bank bur the results are not really encouraging. Maybe it's because his majors are International Finance and Banking.
Tim, it may be better to contact Jonathan through his email address above. I am not sure whether he reads the forum any longer although I am pretty certain he continues to work in Kyiv.
International Finance and Banking is also very useful outside of banking. Our daughter uses her similar skills working for a large company that imports fish, shell fish, crabs, lobsters and so on for canning, bottling, sushi, shashimi and whatever else you can do with fish. Expertise in this area is very useful within the larger organisations.
For an internship, it may be better to cold call around those companies you feel may benefit both your son and the companies themselves.
Good luck.
