.NET/C# Interview Masterclass- Top 500 Questions (PDF)(2026) (Udemy.com)

I've been doing this for 22 years. And while I'd consider this more of a beginner's interview prep, I'd definitely suggest going through all the sections aside from the coding problems. Personally, I really needed the refresher on a number of topics. Well done and very clear and easy to follow!

Yes, this course is absolutely work for me. Now I am preparing for the dotnet developer interview and learning with this course save time to search interview questions and answers in google. I'm so great to see this and hope to bring the best results for my upcoming interview journey. Thanks.

It's a must do course for anyone preparing for interviews for .NET Developer role. The best thing is that its not just a simple list of interview questions, but a complete Crash Course instead. You will be able to learn all the most important topics & concepts in a sequential manner along with their use in real projects. This way you will have crystal clear concepts and will be able to impress the interview with your crisp knowledge. JUST DON'T THINK TWICE BEFORE BUYING THIS COURSE ! Trust me it will be a great investment for your career. Great thanks to Happy Rawat sir for creating this valuable course and sharing his knowledge and experience with us!

This course comprehensively covers most interview questions. I like the fact that Happy doesn't beat around the bush and give a straightforward and brief answer. Which is great!! But I feel he could add few more questions and interview programs which will help the students to practice the learned concepts.

It is very useful and easy to understand . It is incredibly informative and well- organized. The step-by-step explanations made complex concepts easy to understand and the interactive mock exercises are particularly helpful for reinforcing learning. Thank you for providing such valuable content! :)

Hi Sir, Thank you so much for making this course. Recently I had an interview for .NET developer role and I prepared all the topics from here. I was successfully able to clear the technical round as all the questions that were asked is covered here. Thank you.

This exactly what I need to crack interviews. If you are new to the market or you do not have a solid foundation on topics in .Net/C#, then it is good for you to take this course. The first 250 questions are basic but important to know otherwise they will immediately know that you are not qualified for the job. The second 250 are advanced questions but I have also seen them in real interviews and you should also know them to stand out from the crowds.

Happy Rawat's course has helped me tremendously. I'm not sure how it works abroad, but in Italy, there's a practice called body rental, where you are 'sold' by your own company to a client, who in turn resells you to another client. If you work for a consulting firm, this is a common practice, and every time a project ends, you may be sent to other clients, so interviews are fairly frequent. Thanks to this course, I've always made a great impression in technical interviews. If you're a junior dev like me, don't stop at basic questions; delve deep and study every topic that this course offers, you'll really stand out in interviews! Whenever I have an interview, I refresh my understanding of the concepts, both through the videos and the PDF that the instructor has kindly provided. Thank you so much, Happy; I am very grateful to you. I hope to one day purchase a more in-depth course on algorithms and data structures that can help us with interviews where live coding and more complex theoretical topics are required!

I am a senor .NET/ASP.NET/ASP.NET MVC developer. These are really great 300 questions, which I also used some of them to ask interviewees before. The author explained each question and list several bullet points. He also tells you how many out of the all bullet points you need to be able to answer to show that you're professional to pass each question.

Extremely poor Audio Quality of Section 3 onwards. Even after setting volume to 100% it is not audible with very good quality digital headset. With analog headset, it is not audible at all whatever you are speakig. Video gets stuck often. Wrong concept is there. You say Interface can have only methods declaration. But the fact is that Interface can have properties, methods and indexers declaration. Candidates rely on you so you should be very cautious of what you explain. There should be no place for any incorrect information. Thanks for your reply. I observed that audio quality is little bit better with android device. I found one more incorrect information. It is regarding your video of Singleton class. Once we make a constructor private of a C# class, its instance can't be created as well as it can't be inherited. You can try yourself. But in your example you have specifically put sealed keyword for the example of singleton class. It will misguide candidates. In pdf page 313, you have written Datareader contains single table. It is incorrect. We can have multiple tables in datareader too. Then we can access each table one by one. do { while(dr.read){.......} }while (dr.next) Moreover your answers generate many cross questions which you have not included in any of your videos. 1. In Bundling and Minification answer, you did not bother to have a mention of bundleconfig.cs 2. In answer related to Filters in MVC, you did not mention the order of preference or how custom action filters are created. Most of the answers are shallow in nature and interviewer can easily find out that candidate is not have concepts clear. One personal suggestion, instead of having videos of less than 1 minutes duration of most of your videos, make it little bit longer and cover every topic well. For now this series is good for just beginners. Not even for mid-level developers.
