Gdansk - good tech univs with very good IT (but not easy ones - you will cry a lot) and good mechanical(?) department. Warsaw is probably even better.
Polish Universities are now among the best in IT around the world.
You mean Jan Madey, Coach
Filip Wolski, Contestant
Marcin Pilipczuk, Contestant
Marek Cygan, Contestant
Krzysztof Diks, Co-Coach the only people who competed are the best at IT? Yes, Warsaw University is known for IT work, but I would rather regard the students than these PhD's professors who competed.
And yes, it takes 7 - 9 years to complete a PhD in Poland for the total amount of time. But why does this come as a surprise to you? It's the same in Italy, Greece, France, Germany, Sweden, England, and in many areas in the US. I'm sure it's the same in many other areas too.
