Applied via Djinn platform. - First round: a quick interview with the recruiter. - Second round: interview with the tech manager about your background. Asked some technical question about the projects I worked. - Third round: technical interview with two engineers. They asked specific questions about Concurrency, Database, Design Patterns, Springboot and Java. The overall experience was very good, people were nice all the time and the questions they asked made sense to the position I applied to. I guess the forth round would be an interview with the client but the recruiter sent me a message telling me the client decided to hire people from Argentina and Colombia instead o Brazil, probably because it's cheaper.
