They are amazing and one of, no, in fact the best in the world, both Poles and Russians. But that's a selection bias. Don't expect to drop there and find streets overflowing with such people eager to work for you in the actual Poland and Russia. The best already found their cozy spots and are not trading them for your offer whatever it might be (and let's face it: you're not going there after the talent but a cheaper talent), given their fears and insecurity (and exploitation) of the local labour market. Or otherwise, found their way out of the country or are actively looking (will I get promoted to your UK HQ in a year or two?).
