Can confirm. I am brazilian. Did a few onsites this end of year. Guess the only one I passed with flying colors? Uber, Brazil office. TC for mid level around 80k dollars. Now that the real devalued even more, maybe 75-70?
Most of my brazilian friends living abroad also cleared said onsites, absolute majority rejected their offers(because they live elsewhere with a currency that has any sort of value).
As a matter of fact, Uber is struggling to fill their vacancies around Brazil. Everyone that can clear said interview are already in Europe/US. So you're only left off with the people that actually want to be closer to their families.
