DataDriven

¿Qué es DataDriven?

DataDriven.io is the free web platform for data engineering interview prep. Your day job does not prepare you for what they actually ask in the interview, so we simulate all four rounds: live SQL against a real database, Python with live execution, data modeling, and pipeline architecture. AI mock interviews run clarifying questions, coding, follow-up discussion, and a hire/no-hire verdict. Real company-specific questions with adaptive difficulty adjust to your skill level.
