Most Asked Cognizant Interview Questions
These questions come up in Cognizant interviews regularly. Each one includes a tip on what the interviewer is actually checking.
What is the difference between a class and an object?+
Preparation Tip
A class is a blueprint, an object is an instance of that blueprint. Use a Car class and a specific car object as an example. Mention that objects have state (attributes) and behavior (methods).
Explain the concept of encapsulation.+
Preparation Tip
Encapsulation bundles data and methods together and restricts direct access to some components. Use private variables with public getters and setters as an example. Mention why it improves security and maintainability.
What is the difference between a primary key and a unique key?+
Preparation Tip
Primary key cannot be NULL and there can only be one per table. Unique key can have NULL values and there can be multiple per table. Both enforce uniqueness.
What is a virtual function in C++?+
Preparation Tip
A virtual function allows derived classes to override the base class implementation. It enables runtime polymorphism. Mention the virtual table (vtable) mechanism.
What is the difference between a compiler and an interpreter?+
Preparation Tip
Compiler translates the entire program at once before execution. Interpreter translates and executes line by line. C uses a compiler, Python uses an interpreter.
Explain the concept of a transaction in databases.+
Preparation Tip
A transaction is a sequence of operations that must all succeed or all fail together. Use a bank transfer example. Mention ACID properties.
What is the difference between a while loop and a do-while loop?+
Preparation Tip
While loop checks the condition before executing. Do-while loop executes at least once before checking the condition. Use a menu-driven program as an example of when do-while is useful.
What is the purpose of the static keyword in Java?+
Preparation Tip
Static members belong to the class, not to instances. Static methods can be called without creating an object. Static variables are shared across all instances.
Tell me about yourself.+
Preparation Tip
Cover your degree, key projects, skills, and why you are interested in Cognizant. Keep it under 90 seconds. Practice until it sounds natural, not rehearsed.
Why do you want to join Cognizant?+

Tell me about a time you worked on a team project. What was your role?+
Preparation Tip
Describe your specific contribution clearly. Avoid saying "we did everything together". Show ownership of a specific part of the project.
Describe a situation where you had to learn something new in a short time.+
Preparation Tip
Pick a technical skill you picked up for a project. Mention the timeline, how you learned it, and what you delivered.
Have you ever made a mistake at work or in a project? How did you handle it?+
Preparation Tip
Be honest. Pick a mistake that shows self-awareness. Focus on what you learned and how you fixed it.
What do you do when you are stuck on a problem?+
Preparation Tip
Describe your actual problem-solving process: break it down, search for resources, ask for help when needed. Show that you are resourceful and not easily discouraged.
Write a program to swap two numbers without using a third variable.+
Preparation Tip
Use arithmetic (a = a + b; b = a - b; a = a - b) or XOR. Mention potential overflow issues with the arithmetic approach.
Write a program to find the sum of digits of a number.+
Preparation Tip
Use modulo and integer division in a loop. Handle negative numbers as an edge case.
Write a program to check if a number is Armstrong.+
Preparation Tip
An Armstrong number equals the sum of its digits each raised to the power of the number of digits. 153 = 1³ + 5³ + 3³.
Write a program to print the multiplication table of a given number.+
Preparation Tip
Simple loop from 1 to 10. Format the output clearly. This tests basic loop and output formatting.
