Candidatei-me online. O processo levou 4 semanas. Fui entrevistado pela Qube Research & Technologies em jan. de 2025
Entrevista
Technical rounds online then if selected "superday" onsite or online where 2 or more interviewers are met (1 hour each). The process is quite clear and smooth. However, out of the 5 interviewers I saw, one of them was very rude, arrogant, made conceptual mistakes, didn't turn his camera on and barely said hello. The others were neutral/pleasant.
