These questions are tailored for freshers applying for roles like Programmer Analyst Trainee. I’ll split them into Technical Interview Questions and HR Interview Questions to align with your YouTube video structure.

Technical Interview Questions

The technical round focuses on programming, OOPS, data structures, databases, and project-related queries. Here are the most frequently asked questions:

Programming Questions

  1. Write a program to check if a number is prime.
    • Tip: Use a loop to check divisibility up to the square root of the number.
  2. Write a program to reverse a string.
    • Tip: Show both iterative (using a loop) and built-in method approaches (e.g., reverse() in Python).
  3. Find the factorial of a number.
    • Tip: Demonstrate both iterative and recursive solutions.
  4. Write a program to check if a string is a palindrome.
    • Tip: Compare characters from start and end, or reverse the string and compare.
  5. Swap two numbers without using a third variable.
    • Tip: Use arithmetic (a = a + b, b = a – b, a = a – b) or XOR operations.

Object-Oriented Programming (OOPS)

  1. What are the four pillars of OOPS?
    • Answer: Encapsulation, Inheritance, Polymorphism, Abstraction.
    • Tip: Give a one-line explanation for each.
  2. What is the difference between method overloading and method overriding?
    • Answer: Overloading = same method name, different parameters (compile-time); Overriding = same method name and signature in a subclass (run-time).
  3. Explain polymorphism with an example.
    • Tip: Use a simple example like a “Shape” class with “draw()” method overridden by “Circle” and “Rectangle”.
  4. What is encapsulation? How is it achieved?
    • Answer: Bundling data and methods; achieved using private variables and public getters/setters.
  5. Difference between abstract class and interface.
    • Answer: Abstract class can have method implementations; interface only has method declarations (pre-Java 8).

Data Structures

  1. What’s the difference between an array and a linked list?
    • Answer: Array = fixed size, contiguous memory; Linked List = dynamic size, non-contiguous memory.
  2. Write a program to find the largest element in an array.
    • Tip: Use a loop with a max variable initialized to the first element.
  3. Explain stack and queue with real-world examples.
    • Answer: Stack = LIFO (e.g., pile of plates); Queue = FIFO (e.g., ticket line).
  4. How do you reverse a linked list?
    • Tip: Explain iterative (using three pointers: prev, curr, next) or recursive methods.
  5. What is a binary search? Write its code.
    • Tip: Mention it works on sorted arrays; show iterative or recursive logic.

Database Basics

  1. What is a primary key? How’s it different from a foreign key?
    • Answer: Primary key = unique identifier for a row; Foreign key = links to a primary key in another table.
  2. Write a SQL query to find the second-highest salary from an employee table.
    • Tip: Use “SELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees);”.
  3. What is normalization? Why is it important?
    • Answer: Process to reduce redundancy and improve data integrity; e.g., splitting tables into 1NF, 2NF, etc.
  4. Difference between DELETE and TRUNCATE.
    • Answer: DELETE removes specific rows (can be rolled back); TRUNCATE removes all rows (faster, no rollback).
  5. What is a JOIN? Explain types.
    • Answer: Combines rows from two tables; types = INNER, LEFT, RIGHT, FULL.

Project-Based Questions

  1. Explain your project—what was your role?
    • Tip: Highlight tech stack, your contribution, and any challenges.
  2. What challenges did you face in your project, and how did you solve them?
    • Tip: Be honest—e.g., “Debugging took time; I used logs to trace errors.”
  3. Why did you choose this technology for your project?
    • Tip: Tie it to efficiency, scalability, or ease of use.

HR Interview Questions

The HR round assesses personality, communication, and fit for Cognizant. Here are the most commonly asked questions:

Personal & Behavioral Questions

  1. Tell me about yourself.
    • Tip: Keep it 1-2 minutes—cover education, skills, projects, and career goals.
  2. What are your strengths and weaknesses?
    • Answer: Strength = “Problem-solving” (with an example); Weakness = “Overthinking” (but show how you manage it).
  3. Tell me about a time you worked in a team.
    • Tip: Use the STAR method (Situation, Task, Action, Result)—e.g., a group project success.
  4. How do you handle pressure or tight deadlines?
    • Answer: “I prioritize tasks and break them into smaller steps—e.g., during my project submission.”
  5. What motivates you to do well in your career?
    • Answer: “Learning new technologies and solving real-world problems inspire me.”
