Let’s go ahead and look at some commonly-asked OOPs interview questions for experienced professionals.
Here’s what we’ll cover in this article:
Knowing answers to commonly asked OOPS interview questions for experienced professionals is important to ace technical interviews.
In this section, we’ll look at some commonly-asked OOPS interview questions and answers for experienced professionals.
This is one of the most common OOPS interview questions for experienced developers.
Some noteworthy benefits of using Object-Oriented Programming include:
Polymorphism is a feature in OOPs where functions, objects, and variables can take multiple forms. This means that classes can have methods and functions of the same name but perform different functions at a given point. There are two types of Polymorphism - Static Polymorphism and Dynamic Polymorphism.
Inheritance is a core Object-Oriented Programming feature where classes can inherit the properties of other classes. This helps developers form associations while coding, helping them eliminate redundancy in code or code blocks.
This is one of the most popular OOPS interview questions for experienced programmers.
Method Overloading is a feature that allows methods to be defined by the same name, but perform different functions within the same class, if the arguments passed are different.
Data Abstraction is another core feature in OOPs that allows developers to display only the relevant information to the user and hide the implementation details. Data ABstraction enables data and information to be kept private and confidential, thereby ensuring the security of the program/application.
Go through Java OOPs Interview Questions to crack coding interviews.
To better understand the type of OOPS questions asked at technical interviews for experienced developers, we’ve compiled this list of 20+ sample OOPS interview questions for experienced developers.
Practicing these OOPs interview questions for experienced programmers will stand you in good stead for your next programming or developer interview. You can also practice the top Interview Questions on Java OOPS Concepts and some mock interviews for better prep.
Q1. What type of interviews requires a strong grasp of OOP fundamentals?
Coding interviews, systems design interviews, and SQL interviews require a strong understanding and grasp of OOP fundamentals.
Q2. What are the core concepts to prepare to answer OOPS interview questions for experienced professionals?
The core concepts to prepare to answer OOPs interview questions for experienced professionals include - Polymorphism, Encapsulation, Abstraction, and Inheritance.
Q3. Are OOPS interview questions for experienced people asked at Java developer interviews?
As Java is an object-oriented programming language, you can expect OOPs interview questions for experienced professionals at senior Java developer interviews.
Q4. Do you need strong OOPs fundamentals to answer coding questions on core data structures and algorithms?
Technical interviews at FAANG+ companies require you to be good at at least one Object Oriented Programming Language to solve coding problems. Hence, it is important to have a stronghold of OOPs fundamentals to solve coding problems on data structures and algorithms at software engineering interviews.
Q5. Which are some programming languages based on the Object-Oriented Programming model?
