I applied online. I interviewed at Sierra Studio (Rio de Janeiro) in Nov 2025
Interview
almost 7 steps including live coding and system design interview. Live coding was about building ai agents without a framework only using open ai sdk. Interview with Head of AI was different than usual for me. They ask about leadership and technical questions about AI enginnering.
