Pros: Challenging, often undefined environments, so you need to figure things out on the go. Low bureaucracy, so things get sorted pretty quickly. No Jetpack Compose for the sake of Jetpack Compose. A sign of a big company that cares about performance and not just using shiny new technology. Unit tests for all logic. It's not that hard, and once you get used to it, 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, with zero failures to go to release. Never saw that working anywhere before. And it's again not a few, but hundreds of tests. Real performers are recognized. Recently promoted from mid to senior using a fast track.

Cons: No B2B employment in Poland at the time of writing.

Pros: Experienced people (A-players) Pretty tough recruitment process. Very thorough code review process. High quality code with an enormous amount of tests and very high coverage. High quality monitoring where every issue or error is treated very seriously. Teams are truly agile; decisions are made very quickly. Free from Microsoft software (no Teams, SharePoint, Windows, nor other crapware). Continuous Delivery process. MacBooks. No Spring Framework, no Lombok, no Maven! GCP, GKE. Revolut People - a great internal platform that covers all employee needs.

Cons: No B2B contracts for Polish workers. Recruitment process was very long. People are usually very busy, and I imagine that junior/mid developers might find it hard to get proper help here.

Pros: It was a really nice place to work. Friendly people, interesting and modern technology, and a very good salary.

Cons: It is a huge company, so you need to adjust to their pace of work.
