TL:DR: In the first interview (HR), speak as if you were with a technitian, even if you think they will get bored or they won't understand. 1h interview in English with HR. They ask you to explain technical concepts like SOLID to them. I gave short explanations with plain words, hoping to give a more complete, technical explanation in the technical interview. RRHH told me I need to improve my explanation for the tecnical interview. A technical interview that I was never called for.
