How do you design error handling in a large Java application: where do you use checked exceptions, where unchecked, and how do errors reach the API client?

~4 min by voice

How to approach it

The interviewer wants to see whether you have a deliberate error-handling policy for the whole application: when to use checked, when unchecked, how not to lose the cause, how an error passes through layers and transactions, and in what form it reaches the API client.
