I applied online. I interviewed at McKinsey & Company (Budapest) in Sep 2012
Interview
After the PST I had to do 3 rounds of separate interviews. Difficulty increases. Instead of a full case interview, they gave me estimation questions to solve in detail.
Everybody was very friendly and the office was beautiful. Unfortunately they did not hire me after the last round...
