Quick revision
Core answer
Practical understanding of Interface Vs Struct Scenario.
Repeating a definition without saying when to use it.
Give one trade-off and say how you would test it.
Interview-ready guide
Interview answer
Interface Vs Struct Scenario is useful when it solves a clear problem in the code. I would first check the input, expected output, and constraints, then choose it if the simpler option cannot meet those needs. For example, I would use it in the part of an application where its main benefit is visible, rather than adding it everywhere. If I were writing this in production, I would keep the implementation small, name the assumption clearly, and cover the important edge case with a test.

Deep Dive & Architecture
When debug a problem involving Interface Vs Struct Scenario causes a problem, I reproduce it with the smallest input I can find.
I check the inputs and the expected result, trace the important state step by step, and add a test for the failure.

A common mistake is giving a definition without explaining a practical trade-off.
