About these ASP.NET MVC questions

ASP.NET MVC is still extremely common in enterprise .NET shops, and interviewers lean on it heavily for developers with 3–5 years of experience. The core theme is the request life cycle: how a URL becomes a route, how the controller and action are selected, how model binding and validation run, how the action result executes and how the Razor view renders.

Expect questions that compare the MVC pieces — ViewBag vs ViewData vs TempData, action filters vs middleware, ActionResult types — and scenario questions about validation, anti-forgery tokens and structuring large controllers.
