Accenture QA Engineer Interview Questions and Answers

Factorial is a mathematical function that multiplies a number by all positive integers below it, calculated using recursion.

• Factorial of n (n!) is defined as n * (n-1)!

• Base case: factorial(0) = 1

• Example: factorial(5) = 5 * factorial(4) = 5 * 24 = 120

• Recursive call: factorial(n) calls factorial(n-1) until reaching the base case

This task involves printing an inverted triangle pattern using asterisks or other characters.

• Use nested loops: The outer loop controls the number of rows, while the inner loop prints characters.

• Start with the maximum number of characters in the first row and decrease by one in each subsequent row.

• Example for 5 rows: ***** **** *** ** *

OOP (Object-Oriented Programming) is a programming paradigm based on objects that encapsulate data and behavior.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class based on an existing class, inheriting its attributes and methods (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the sam...read more

SDLC stands for Software Development Life Cycle, a process used by software development teams to design, develop, and test high-quality software.

• SDLC is a structured process that consists of several phases including planning, analysis, design, implementation, testing, and maintenance.

• Each phase has its own set of activities and deliverables that contribute to the overall success of the software project.

• Examples of...read more

Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

• Performed after code changes to ensure existing functionality still works

• Helps catch bugs introduced by new code changes

• Automated tools can be used to streamline the process

• Can be time-consuming but is essential for maintaining software quality
