ASP.NET MVC Interview Questions

In this article I am sharing questions related to ASP.NET MVC. I have made list of most frequently asked questions. These questions are generally helpful for candidate having overall 2-5 years of experience(except TDD) out of which at least one project or six months in ASP.NET MVC. The candidate who are aspirant for lead role should focus more on security, authentication and authorization, filters, DI, design of best grids, scenario based(challenge faced or achieving particular functionality or he/she will give you scenario what actually he/she is facing or faced) along with below questions.

Sometimes candidates does step by step(just copying and pasting) assignment from other blogs and try to showcase experience(fake) on ASP.NET MVC. I would suggest those candidate to understand the concept first and then try to implement small CRUD based application by designing own approach.
