Technical Proficiency – You must be comfortable discussing data workflows, software integrations, and metrics tracking. Interviewers look for evidence that you can navigate technical environments without constant oversight.

Operational Efficiency – Duetto values candidates who demonstrate a structured approach to their work. Be ready to explain your personal system for managing tasks, tracking metrics, and ensuring nothing falls through the cracks during busy periods.
