What are the roles of Model, View, and Controller in ASP.NET MVC?
PICTURE THIS: A REST CALL
ClientGET /users/1
ServerFind row
JSON back200 OK
Simple meaning
Model holds data and domain rules.
WHY — MVC instead of guessing?
Why interviewers care about MVC:
MVC questions separate people
who only read docs from people who shipped.
Keep it short, concrete,
and tied to .NET MVC work.
Stay structured
Name the idea, why it exists, then one short example.
Close cleanly
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Model holds data and
domain rules.
- 2Why it exists
View renders HTML.
- 3Controller accepts HTTP, talks
to services, and chooses a view or redirect.
- 4Clear separation keeps UI
and logic maintainable.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
