Tech, more than likely, contributes towards personal experience. I can safely say this about Portugal: this is a country where companies do not want to invest in a tech department. There is a culture of outsourcing all tech related work. This has caused the birth of manyyy "outsourcing tech companies" - the sort of companies that hire tech talent just to shift them over to "projects", where you go to work for someone else and are at the complete mercy of the client (who demands the world since they have an expensive contract with the outsourcing company).

This has been my woe, and the same can be said about many of my friends and uni acquaintances. I suspect other fields might not have it this badly.

I have found a completely different culture here in the UK, there is so much demand for tech workers, combined with a much better approach towards companies investing in tech - it feels like the worker has that much power, if I'm not happy I can just go get a job somewhere else, probably within a week of quitting. It's a very different dynamic when compared to Portugal: Jobs are scarce and the pay isn't great. Tech is non-innovation driven, you're not there to think about the future, just to fix present issues that are very specific to some random company.

I don't miss Portugal at all when it comes to work.
