Practice writing migrations, configuring relationships, and using raw SQL when necessary. Know how to optimize queries and handle transactions.
Explore RESTful design principles, input validation, pagination, and securing APIs with JWT or OAuth. Learn about versioning and best practices for maintainable APIs.
Learn the basics of Blazor components, Razor pages, and how front-end code integrates with backend APIs.
Be prepared to write joins, stored procedures, indexing strategies, and understand how to optimize queries for performance.
Understand patterns like repository, unit of work, factory, and how to structure layered applications for scalability and maintainability.
Rather than reading random question lists, create a structured study plan covering fundamentals, applied coding, and real-world scenarios. For example:
Interviewers look for candidates who can think critically, communicate clearly, and show real understanding. With guided preparation, you can:
Combine clear understanding with modern best practices to tackle HR screening, coding rounds, and deep technical interviews alike. Focus on writing clean, maintainable, and testable code while keeping up with the latest .NET updates.
Interview preparation isn't just about passing the next testβitβs about becoming a better, more confident developer ready to grow in your career. Learn deeply, practice smartly, and prepare to communicate your ideas effectively. With dedication, you can crack even the toughest MNC technical rounds and unlock exciting opportunities in modern .NET development.

Mr. Sudipto Mukherjee is one of the best instructors I have ever come across. His way of training is nothing short of art. He will teach you why you need or not need to write a piece of code rather than just saying that it should be done, and that makes coding enjoyable and the code very performance oriented. If you want to really learn, you have to really become his friend... He will then take you to the deep end. I am saying this from personal experience.... Just one thing... He does not come cheap, but you get much more than what you have paid for.

Excellent tutor! Let's just say that as a bio-math student, I had next to no experience at coding. A few classes with Mr.Sudipto, and bam! His teaching methods are extremely student-friendly and interactive - The classes are never monotonous, and every new task he presented was an interesting one to look forward to. Within no time, I could write programs of my own. Definite recommend!! ππ»
