The interviewers had already decided on their candidate but proceeded to go through with the interview for formalities. I was constantly cut-off mid-sentence, they gave me no opportunity to ask them questions and they showed no interest getting to know me. The interview was suppose to be an hour long but they cut it to less than 10 minutes. It was a complete waste of time. Is this what JetBlue does to all their candidates?

Answer: Aggregation is best defined as the entity reference where it represents the relationship between two classes where the aggregate class contains a reference to the class which it owns. Aggregation represents a has-a and whole/part relationship. For example consider an aggregate class Employee stores information such as name, age, salary, and the Address class stores information such as city, state, and pin-code. Now, if the Employee class is defined to contain an Address object then it will be said that the Employee object has-a Address object. The Address object also makes up part-of Employee object – there is no employee without any address to live. Therefore, the Employee object owns the Address object.
