Pretty sure salaries at large tech companies are way higher in places like London, Zurich or Amsterdam than in Warsaw or Prague for example. Berlin may be closer to the eastern countries.

It might help to discuss actual ranges instead of "intimate experience" so we can tell if your experience matches reality.
