Happy Birthday Sir.Questions I faced in Interview, Could you please answer these question that will be really helpful. 1. There is a scheduler that runs every thursday to import data from CSV file in FTP server to User table. CSV file will contain new user or updates to existing user or existing user deleted. There is no flag in csv file to identify whether it new or existing or removed. How do you design a system to import file to table with less I/O. 2. we have service which calls multiple different API, If any one api call fails how do you make sure other API calls are not committed ? 3. What is clean architecture and when do you use it? 4. What is CQRS design pattern and why we need to use? 5. There is an application which is running in Dev and QA environment, How to configure authentication for this application such that Dev environment uses AD authentication and QA environment uses Forms Authentication or any other authentication.? 6. What is Repository pattern and Unit of Work why do we need to use it? 7. Entity Framework VS Dapper which one do you choose for your project and why? 8. Can we have EDMX file and Code First approach in same project? 9. Difference between Adapter and Decorator pattern? 10. How do you plan and migrate the existing application to Azure Cloud? 11. Azure App service vs Azure Function

[@questpondvideos]

[@tj_r_3679]

We need more content on Design patterns. Plus, an additional Note: You can do a follow up series on How we can combine the design patterns together to implement a hypothetical/real world solution to a problem would be the best way to go in my opinion. Thank you again for your videos. I have learnt so much just from your videos. Happy Birthday to you.

Hi Sir, thank you, can you please make a class on technical leader job interview! For Embedded systems technical leader position!!

[@provofficial1]

Hi Sir, I got question related to Adopter , Bridge and Façade Pattern and They asked me its all wrapper then why do need all these ? If you can explain about it more ?

[@questpondvideos]

Bridge and Facade surely do not look like wrappers but Adapter does come does have some resemblance . But please note its not just about creating a wrapper the whole point is to make incompatible interface compatible. And Adapter has two flavors Object adapter and other class adapter. Object adapter looks like a wrapper but not class adapter as it uses inheritance. And please note Adapter pattern adheres to interface but a normal wrapper class is just a aggregation.

[@tronggia_70]

Dependency Injection is design pattern. Dependency inversion is architechture pattern. Inversion of control is architechture style. Please correct me

[@questpondvideos]

Yes , DI is a pattern yes or must be to be more specific constructor injections ,, property DI injection . I think one more keyword we should add here design principle. DINV and IOC are Design principle. design principles guide the design of individual components, ensuring they are well-organized and adhere to best practices. On the other hand, architecture styles guide the overall structure of the entire software system, determining how different components and modules interact at a higher level. While design principles are concerned with the "how" of designing individual parts, architecture styles focus on the "what" and "how" of organizing and structuring the entire system.

for 52:00 if we remove null check inside lock then also it will be a lazy loading and it entered here because it is null in first condition. in between how it can become null

[@amitaec]

Buddy, it will create a performance issue if you don't have an outer null check. More thread, try to acquire for lock.
