Problem
Data professionals often struggle to prepare for technical interviews because they lack access to authentic, company-specific coding and conceptual questions, as well as tools to practice and receive detailed feedback on their solutions.
Solution
StrataScratch offers an online platform that aggregates over 1,000 real interview questions from more than 200 companies, including Google, Meta, and Amazon. Users can solve SQL and Python challenges in an integrated code editor that supports multiple SQL dialects (PostgreSQL, MySQL, MS SQL Server, Oracle) and popular Python libraries (Pandas, PySpark, Polars). The platform also provides non‑coding interview material covering system design, product sense, business cases, statistics, and behavioral topics. After submission, an AI evaluator scores answers on completeness, accuracy, depth, structure, and practical relevance, delivering actionable improvement suggestions. Additionally, an AI‑driven mock interview mode tracks timing and simulates a real interview environment, helping users build confidence and a portfolio of solved problems.
Target Audience
Primary users are aspiring and current data scientists, data analysts, and data engineers who need to practice technical and non‑technical interview questions to secure roles at tech companies.
