All Software Engineering Interview Questions (78)

Scroll through every important Software Engineering question asked in real interviews. Includes MCQs, subjective questions, and coding prompts.

1. Which of the following best defines Software Engineering?

Difficulty: EasyType: MCQTopic: SE Basics

Writing code only
Designing, developing, testing, and maintaining software systems in a disciplined way
Only testing software
Maintaining hardware infrastructure

Software Engineering is a multidisciplinary field that covers not just coding, but the full lifecycle of software: requirements gathering, design, development, testing, deployment and maintenance. Interviewers expect you to recognise that it is more than just programming.

Correct Answer: Designing, developing, testing, and maintaining software systems in a disciplined way

2. Which classification is often used when referring to software types in Software Engineering?

Difficulty: MediumType: MCQTopic: SE Basics

Application software, system software, embedded software
