Ruby exception handling interview questions test whether you understand how errors propagate and how to handle them safely. This module covers the begin/rescue/ensure/end structure, raise with a message string vs raising a specific exception class, how to capture the exception object with rescue ErrorClass => e, the standard exception hierarchy (Exception → StandardError → RuntimeError — rescue catches StandardError and below by default, so never rescue Exception), ensure always runs (like finally in other languages), retry inside a rescue block with a counter to prevent infinite loops, defining custom exception classes with class PaymentError < StandardError; end, and the rescue statement modifier for simple one-liners. Every answer explains the why — what happens at runtime, not just the syntax.
