12 in-depth manual testing interview questions

Review the following manual testing questions to be better prepared for interviews:

1. What manual testing skills qualify you for this position?

Employers expect you to have certain skills to succeed in your manual testing position. By asking this, an interviewer wants to know whether your skill set aligns with the organization's expectations. After listing your manual testing skills, provide examples of how you apply each one.

Example: "My hard and soft skills qualify me for this position. With three years of work experience as a software tester, I have well-developed analytical skills and extensive knowledge of computer systems. I apply them when examining computer programs and identifying bugs. I'm also good at communicating my findings with clients and discussing coding challenges with colleagues. My organizational and time management skills help me manage my time when manually testing multiple software applications."

2. What are the advantages of manual testing over automation testing?

Software testing is either manual or automated. Interviewers ask this question to find out more about your expertise and understanding of both software testing types. Use layperson terminology when answering this question.

Example: "Unlike automation testing, manual testing allows for human observation to find software glitches. It also improves the customer experience. In my career, I noticed employers prefer manual testing when they need to run test cases once or twice because it's cost-effective."

3. Why is documentation in manual testing important?

Documentation helps you avoid recurring software bugs and leads software developers and engineers on what to improve. It also helps in estimating your testing effort and the test's coverage. In your response, show interviewers you understand the role of documentation in manual testing.

Example: "Documenting details such as the organization's rules, configurations, code changes, test plans, test cases, and bug reports helps to save time and cost. I also find it useful for tracking changes and communicating test results to the engineering team or upper management. From my research, I understand your organization values software documentation. I'd be happy to prepare one for each test case I work on."

4. What are the differences between white-box testing and black-box testing?

This question aims to assess whether you understand the methods for software testing. Explain each method in layperson words and consider using analogies to emphasize your expertise as a manual tester.

Example: "Black-box testing requires you to understand the structure, design, and programming code of what you're testing in advance. In comparison, you don't need extensive knowledge of what you're testing when performing white-box testing. I remember the difference between the two by thinking of black-box testing as working in a dark room and white-block testing as working in a well-lit room. In a dark room, I need to know the structure and code of each test case because I can't see them. A well-lit room allows me to see more clearly."

5. What do you include in a test plan?

Interviewers ask this to assess your knowledge of various testing documents. They want to identify candidates who have experience using test plans. Start by defining a test plan and the information you write in one.

Example: "A test plan is a document that details the objectives, resources, and processes for a software test. It describes the overall workflow, and I include the software product's description, objectives, testing strategies, scope and schedule, testing resources, and deliverables in it. At my previous job, my team used a test plan to describe the testing schedule and other testing activities."

6. How do you determine time estimations for manual testing projects?

With this question, an interviewer seeks to evaluate your time management and organizational skills. Answering it convincingly also displays your ability to plan and execute projects effectively. Describe each step you follow in determining the time to complete each testing project.

Example: "Various factors, such as lack of data or resource availability, can affect time estimations. I start by identifying the required tasks. Then, I divide these tasks into smaller tasks that I may delegate or handle myself. Finally, I estimate the time to complete each small task and add extra periods for possible issues. I feel it's important to always meet deadlines, anticipate issues, and communicate accurate time estimations."

7. Can you explain the purpose of end-to-end testing?

The goal of this question is to gain more insights into your basic software testing knowledge. When answering, describe what end-to-end testing means, when to implement it, and why it's beneficial.

Example: "End-to-end testing means testing a software program from start to finish. The purpose of end-to-end testing is to assess a software program and how a customer would use it in a practical environment. I use this procedure to catch software bugs and identify software integrity issues."

8. What are the types of manual software testing?

Interviewers ask this to assess your knowledge of various types of manual software testing, when to use them, and their benefits. Answer this question by giving listing the types of manual software testing you have experience performing.

Example: "In my three-year career, I've performed integration tests and system tests. I'm also familiar with unit testing, agile testing, API testing, and installation testing. While some types are suitable for small lines of codes, others are ideal for complete system tests."

9. How would you handle conflict with a team member on a software testing project?

As a manual tester, you may face occasional disputes with team members. This question offers you the opportunity to describe how you handle conflicts. Interviewers look for candidates who can work through issues without allowing them to affect the team's productivity.

Example: "I understand my role requires me to handle conflicts that may arise between other team members effectively. I'd start by calling all involved parties to a private conflict-resolution meeting and listening carefully to each member's concerns. I'd encourage everyone to express themselves if I'm the mediator, and identify a mutually beneficial solution. Over my career as a software tester, this conflict-resolution approach helped me thrive in various workplaces and build healthy relationships."

10. Describe how you conduct manual software tests.

Your response to this question reveals whether you understand the standard procedure for manual testing. Start by listing out the steps and explaining what each entails.

Example: "The first manual testing step is to plan the project. At this stage, I determine what tasks to complete and identify the required resources. I also consider all variables, such as managerial factors and the absence of historical data. Next, I analyze and design the work plan. Then, I start implementing and executing the software testing project. Next, I evaluate the exit criteria and start documenting everything that occurred. Finally, I carry out test closure activities and communicate my findings to the engineering department and upper management. I introduced this approach to my previous employers at HiltonX Software Inc."

11. Differentiate between software verification and validation in manual testing.

By asking this question, interviewers want to find out whether you understand basic software testing terminology. Explain the differences clearly, and consider using examples.

Example: "While verification is a static process, validation is dynamic. That means you don't need to execute programming codes during verification, unlike validation. Reviews and inspections are examples of verification, while functional testing techniques are examples of validation."

12. Why do you want to work here as a manual tester?

Interviewers ask this question for various reasons. First, they want to find out whether you researched the company and understand what it does. The question also offers interviewers insights into your long-term career goals as a manual tester. Ensure you show your enthusiasm for the position and why you feel you are a good fit for the organization's culture.

Example: "While I enjoyed testing software programs with my previous employer, I feel I need to work on more exciting challenges. This position offers the opportunity to execute manual tests on social media software, which is thrilling. The opportunities for career development and networking also appeal to me, and I'd love to join the team."
