While I don't have doubts about this being a good way to find rough outlines for compensation, I'm yet to find a reliable source of data for Europe. Has anyone else had better luck?
in the UK, junior is £20-40k, mid-level is around £40-60k, lead can be around £60-100k. Very rough numbers, and adjust upwards slightly for London. The big money is in contracting in the UK, which would be our accessible FAANG-equivalent.
There are also a couple of local non-FAANG companies that pay similar salaries.
