HEAR FROM SATISFIED STUDENTS

Yifan Yao : ” The course covers everything from SQL basics to window functions and complex query optimization, giving me a comprehensive understanding of SQL. The Python module is also solid, helping me master everything from basic syntax and OOP to data structures and data frames. In the Data Modeling section, the instructors provided detailed explanations of key concepts like database structure, keys, relationships, and normalization, completely transforming my understanding of data design.” “ What really stands out is the AWS Data Warehousing part. With DrillInsight's platform, you can directly work with cloud environments without the need for additional setup, and by following the instructors, I learned how to build data lakes, ETL pipelines, and manage historical data. The course not only covers all the essential skills needed for top-tier company interviews but also reinforces our understanding with practical case studies. The instructors’ teaching approach is crystal clear, and after the course, I not only understood the concepts but also the reasoning behind them—especially the ‘ why.’ It even boosted my confidence with system design interview questions, and I almost blew the interviewer away with my knowledge, haha!”
