There were 4 people from different titles in the company involving different aspects of the job like an HR rep, a Senior developer, the branch director and a product manager. Hr rep and the director asked questions about analytical thinking whereas the senior developer and the product manager focused mainly on java skills, SOLID principles and OOP. After that, there was a brief English speaking phase (was not hard at all). Overall, the interview had quite fair questions for the title and a fluid, relaxed state.
