Have you noticed how cliché some questions are in the interview? And we are not talking about one interview in particular as it happens again and again. For example; they ask “where do you see yourself in the next 10 years”? or even worse “what are your strengthens and weaknesses”?

As much as these irritate you, they are important because they actually give some important clues about your current state of mind, your perspectives, and future expectation from life. When confronting these questions, you need to be very careful as you may accidentally reveal something that you regret later. It is similar to the academic projects you have submitted with help for programming assignments during college time.

Here, We will Discuss Similar types of Questions in the programming world;

What are the key principles of object-oriented programming?

It is one of the most common questions that developers cannot allow themselves to not know. Most of the time, junior level or beginners have to confront this question during an interview, why? Because it allows interviewers to tell three things about the candidate.

First; did the candidate did his homework for this interview? 

If the interviewer receives the answer on an immediate basis, then it indicates that the candidate is serious about it.

Second: Did the candidate has passed the tutorial phase?

Having a basic understanding of the principles of object-oriented programming shows that you have crossed the copy-paste phase and now you see things from a higher perception.

Third: is the candidate have a deep or shallow understanding?

This question allows interviewers to test the candidate for other development subjects.

There are four major principles of object-oriented programming (OOP) namely;

  • Encapsulation
  • Abstraction
  • Inheritance
  • Polymorphism

These four words may sound scary for beginners and they may find a long description on Wikipedia which can make the whole scenario even more complicated. Therefore, the candidate must prepare a short, simple, informative, and clear explanation of these concepts like what they did with the programming assignment writing help service in Liverpool.

The explanation you will prepare may sound like something you explain to a 5 years old child but interviewers would love to hear them. While explaining the concepts you can take some real-world examples. For instance; you can explain class as a vehicle. Now you can ask what do you think about the vehicle? They might say vehicle like car and truck. Now, you can them to differentiate them? They will surely mention size, purpose, and other things. Well then explain the OOP has different classes that contain different variables and methods that are different from each other.

Example like this work the best in the interview.

What is next?

To properly prepare yourself for the interview, you need to clear your basic programming concepts. Once done, you need to practice them on a regular basis as the majority of the interviews asks candidates to do some coding in front of them to prove their expertise.
