business quality assurance analyst Interview Questions and Answers

1. What is the difference between QA and testing?

   • Answer: QA (Quality Assurance) is a broader concept encompassing all activities to ensure quality, including prevention of defects. Testing is a subset of QA, focusing specifically on finding defects through various testing methods.

2. Explain the Software Development Life Cycle (SDLC).

   • Answer: SDLC is a structured process for planning, creating, testing, and deploying software. Common models include Waterfall, Agile (Scrum, Kanban), and Spiral. Each stage involves specific activities like requirements gathering, design, coding, testing, deployment, and maintenance.

3. What are the different types of software testing?
