Answer
Use constructors to enforce invariants. Frame the concept in practical terms so you can explain it during interview discussion.
Ensuring that value objects are created in a valid state is critical. Constructors should enforce invariants to prevent invalid objects. For example, an 'Email' value object should verify that the address is valid when constructed, preventing incorrect email usage in the system.
