Yes, the Research Gate portal is helpful in finding an interesting job at a university, a research institution operating in another country. On the Research Gate portal, scientists and researchers, research and teaching staff, teachers, etc. can view job offers from universities, research institutes, other teaching and / or research institutions operating in different countries. These offers come from various countries around the world. On the other hand, if certain universities, research institutes, etc. have the opportunity to present their job offers of academic teachers, research and teaching staff, scientists and researchers, which may reach interested persons operating in other countries, on other continents. Therefore, it is a very big advantage and a positive function of the Research Gate portal.
I think, it is far from that (to get job because of RG) for many researchers in developed countries, however, there have to be positive facts. Waiting for announcing of them from other researchers.
