FAANG companies don't pay anything near 300k USD annually in Europe, it doesn't happen. Probably 20% above the local market average. Their (certainly Google's) recruitment process in Europe is still the same demanding though. These are yet another companies in one's job application queue, and annoying ones.
Developer salaries are notoriously low in Europe and I’m not even camparing crazy SV or NYC salaries. I worked with devs in Europe working on the same platform and domain as me for half the salary. I haven’t heard of many low 6 figure developer jobs in and around the EU.
