Q:

Are you comfortable offering our charge account to customers?

Answer

A candidate should not be shy here. Someone who tells you that they are uncomfortable when being solicited for proprietary charges by other retailers will not be successful in your organization. If that is something that you as a candidate struggle with, make sure that you portray your desire to succeed. Tell the employer that it is something that you are gaining skills on, and would love the opportunity to perfect your script.

Q:

When should I use abstract classes and when should I use interfaces?

Answer

Use Interfaces when…


- You see that something in your design will change frequently.


- If various implementations only share method signatures then it is better to use Interfaces.


- You need some classes to use some methods which you don't want to be included in the class, then you go for the interface, which makes it easy to just implement and make use of the methods defined in the interface.


 


Use Abstract Class when…


- If various implementations are of the same kind and use common behavior or status then abstract class is better to use.


- When you want to provide a generalized form of abstraction and leave the implementation task with the inheriting subclass.


- Abstract classes are an excellent way to create planned inheritance hierarchies. They're also a good choice for nonleaf classes in class hierarchies.
