DataDriven이란?

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.
