Why is Ruby known as a language of flexibility?
This is an important Ruby interview question. Ruby is recognized as a flexible language since it allows its author to change the programming parts. Some aspects of the language can be deleted or redefined. Ruby does not impose any limitations on the user. To add two numbers, for example, Ruby allows you to use the + sign or the word 'plus'. This modification is possible using Ruby's built-in class Numeric.

What is the difference between the Observers and Callbacks?
Rails Observers: Similar to Callback, Observers are used when the method is not directly related to the object lifecycle. In addition, the observer has a longer lifespan and can be detached or attached at any time. For example, displaying model values in the UI and updating the model based on user input.
Rail Callback: This method can be called at specific points in an object's life cycle, such as when an object is validated, created, updated, or removed. A callback is a short-lived method. For example, consider operating a thread and providing a call-back function that is invoked after the thread terminates.
