I really like the way it expands based on the level of the answer and how it follows up with tail questions to verify! The lecture on the AI era at the end was also particularly informative.

These answers get straight to the point. Studying by looking at the Q&A and then searching for additional information really helps me learn well.

I highly recommend this to those who felt stuck during interviews despite thinking they knew the material. It was a huge help in comparing answers by level (Bronze/Gold) and establishing a framework for giving concise, pointed responses.

I was highly satisfied because the Java lectures made it easy to organize important concepts, and now you've released a DB course!! Thank you for clearly explaining transactions, locks, concurrency control, and various issues that can be encountered in actual production environments! This is a masterpiece of a lecture that provides a great roadmap for student developers like me!

The way it directly compared good and bad answers from an interviewer's perspective was different from other lectures. Thanks to that, I got a sense of which direction to take with my answers, and the provided materials were so well-organized that they were perfect for a quick review right before the interview!
