Top 10 Questions for Quality Assurance Tester Interview

1. Explain the SDLC lifecycle and your role as a QA Tester in each phase?

The SDLC lifecycle typically consists of the following phases:

• Requirements Gathering: During this phase, the QA Tester assists in defining the project’s scope, identifying user needs, and documenting the functional and non-functional requirements.
• Design: The QA Tester reviews the system design and architecture to identify potential areas for defects and ensure that the design meets the user requirements.
• Development: The QA Tester collaborates with developers to ensure that the code is developed according to the requirements and design.
• Testing: The QA Tester executes test cases, identifies and logs defects, and verifies the system’s functionality against the requirements.
• Deployment: The QA Tester assists in testing the system in a production-like environment and ensures a smooth transition to live.
• Maintenance: The QA Tester supports ongoing maintenance and enhancement activities by creating test cases, performing regression testing, and monitoring the system’s performance.

2. Describe the different types of testing you have performed and how you prioritize them?

Functional Testing

• Unit testing
• Integration testing
• System testing
• Acceptance testing

Non-Functional Testing

• Performance testing
• Load testing
• Security testing
• Usability testing

Prioritization of testing types is based on risk assessment, which considers factors such as the impact of defects, the likelihood of defects occurring, and the availability of resources.

3. What is exploratory testing and how do you approach it?

• Exploratory testing is a style of testing where the tester interacts with the system in an ad-hoc manner, without predefined test cases.
• Approach:
  • Identify areas of interest based on knowledge of the system.
  • Explore the system by manipulating inputs and observing outputs.
  • Record observations and identify potential defects.
  • Document findings and share them with the team.

4. How do you design test cases and what are the different design techniques you use?

I use the following techniques to design test cases:

• Equivalence Partitioning: Dividing the input domain into equivalence classes and selecting one representative value from each class for testing.
• Boundary Value Analysis: Testing the limits of the input domain, such as minimum, maximum, and special values.
• Cause-Effect Analysis: Identifying the logical relationships between the inputs and outputs and creating test cases to verify the expected outcomes.
• Risk-Based Testing: Prioritizing test cases based on their risk and impact on the system.

5. What is your process for reporting defects and how do you ensure they are resolved effectively?

• Log defects in a centralized system, including details such as the defect description, steps to reproduce, and priority.
• Communicate defects to the development team clearly and concisely.
• Track the status of defects and follow up with the development team to ensure timely resolution.
• Verify that defects have been fixed by re-testing the system.

6. How do you stay updated with the latest testing trends and technologies?

• Attend industry conferences and webinars.
• Read industry blogs and articles.
• Experiment with new tools and technologies.
• Participate in online communities and forums.

7. What are some common challenges you have faced as a QA Tester and how did you overcome them?

• Time constraints: Proactively planning and prioritizing testing activities, using automation tools, and working closely with the team to manage expectations.
• Lack of clear requirements: Clarifying requirements with stakeholders, conducting user interviews, and using exploratory testing to cover potential gaps.
• Technical complexity: Acquiring necessary technical skills, collaborating with developers, and using appropriate testing tools to validate complex systems.

8. How do you handle conflict or disagreement with a developer or other team member?

• Approach the issue respectfully and professionally.
• Present evidence and data to support my position.
• Listen actively to the other party’s perspective.
• Collaborate to find a mutually acceptable solution.
• Escalate the issue to management if necessary, but only after attempting to resolve it directly.

9. What is your experience with Agile development methodologies and how do you adapt your testing approach?

• Experience with Agile methodologies such as Scrum and Kanban.
• Adapt testing approach by:
  • Writing user stories and acceptance criteria based on the requirements.
  • Creating test cases that align with the sprint goals.
  • Using continuous testing and automated testing tools to provide rapid feedback.
  • Collaborating closely with the development team in daily stand-ups and sprint planning meetings.

10. Describe your testing experience in a cloud environment and the challenges you encountered.

• Experience in cloud-based testing platforms such as AWS or Azure.
• Challenges:
  • Maintaining test data integrity and security in a multi-tenant environment.
  • Dealing with dynamic infrastructure and ephemeral resources.
  • Ensuring test coverage in a rapidly evolving cloud ecosystem.
