Pros
Challenging - often undefined environment, so you need to figure out stuff on the go.
Low bureaucracy - things get sorted pretty quickly.
No jetpack compose for the sake of jetpack compose. A sign of big company which cares about performance and not to just use shiny new technology.
Unit tests for all logic - it's not that hard, once you get used to it - becomes a habit and you don't treat this as extra work. Never saw anything like that anywhere. Hundreds of thousands of unit tests.
UI tests which are not flaky - 0 failures to go to release. Never saw that working anywhere before. And it's again not few but hundreds of tests.
Real performers are recognized. Recently promoted mid to senior using fast track.
Cons
No b2b employment in Poland at the time of writing.
