Interview Query
Practice-question and course platform for data science, analytics and data engineering interviews, with company-specific interview guides.
Interview Query is a practice-question site for data interviews, covering SQL, Python, statistics, machine learning, and product-sense/case-study questions, with solutions and an in-browser code runner. Its differentiator is breadth of company-specific content: over 1,600 company interview guides describing what a given employer's data interview loop actually looks like, alongside take-home-style challenges and 40+ hours of course content on interview topics. Like StrataScratch and DataLemur, it assumes existing SQL/Python competency and is meant for interview drilling rather than teaching concepts from scratch. It is cloud-only, sold as a subscription (monthly or annual) or a one-time lifetime-access purchase, with no free full-question-bank tier.
