Romania? That’s why companies go there and other distant countries. To pay below market rate with huge press support. I experienced it first hand from Continental and Hella. If I have the same job in Germany, I will get normal salary. If I take job in eastern branch, I will get 1/3 salary. And local companies offered me 1/2. Obviously I stayed in Germany.
Faang salary only exists on the US. Even the richest countries in Europe don't have those salaries for programmers (maybe if you work on finance or some niche subject).
On average, I would say a senior would get between 3k and 4k euros in RO, at a regular company. It depends a lot on city too. In bucharest salaries should be higher.
Obviously Amazon thinks that mortages can be paid just by flexing their employee badge.
