You have some knowledge of Python and SQL. If not, then refer to our Data Science Interview Questions and Answers - Part 1. Landing a Senior Data Scientist or ML Engineer role requires more advanced-level preparation: it demands fluency in modern Deep Learning, expertise in the data stack, and the ability to solve complex business case studies. This is the leap most candidates fail to make.
Welcome to Our Advanced Data Science Interview Qs, the ultimate final stage preparation course. Part 2 delivers 6 rigorous practice exams covering the high-level, cutting-edge topics that define senior-level roles across global tech companies. This is your chance to move from simply knowing concepts to proving your strategic, business-ready expertise.
This structured series is built for modern technical interviews and is split into four essential modules:
Deep Learning (Tests 1 & 2): Don't just recite definitions. We test your grasp of Transformers, Attention Mechanisms, GPT/LLMs, and the crucial ethical applications of Generative AI. This is the future of the field, and we ensure you speak the language fluently.
The Data Tool Stack (Tests 3 & 4): Master the tools that run the business world. Drill down on Excel's Power Query and modern BI platforms like Power BI and Tableau. Learn DAX functions and Row-Level Security—skills that prove you understand data governance.
Big Data & Data Engineering (Test 5): Technical interviews increasingly focus on data pipelines. Practice questions on ETL, Parquet, Hadoop, Spark basics, and how to architect solutions on major Cloud platforms (AWS/GCP/Azure).
Case Studies & Soft Skills (Test 6): This final exam is your most valuable. We force you to apply your technical skills to real business case studies (forecasting, churn). Crucially, you will master the STAR method and the leadership framing required to ace the HR/Behavioral questions—the step that often seals the deal in any GEO location.
Enroll now. If you are ready to stop interviewing for entry-level roles and start leading technical teams, this is your final, essential preparation.
