During my last job, I was responsible for both types of testing, so I learned how to do each one effectively.”

What are some of the most important qualities for a testing technician to have?

This question can help the interviewer determine if you have the necessary skills and abilities to succeed in this role. When answering, it can be helpful to mention a few of your most important qualities and how they relate to the job.

Example: “The two most important qualities for me are attention to detail and problem-solving skills. As a testing technician, I am responsible for ensuring that all data is accurate and complete. This means I need to make sure I’m paying close attention to my work at all times. In addition, when something goes wrong with a test or there’s an issue with the results, I need to use my problem-solving skills to find solutions.”

How would you go about testing a new product prototype?

This question can help interviewers understand your testing process and how you apply it to new products. Use examples from past projects that show your ability to work with new prototypes and test them effectively.

Example: “When working with a new product prototype, I first assess the specifications of the project and determine what tests are necessary for the client’s needs. Then, I create a plan for each test based on the specifications and requirements. For example, in my last role, I worked with a company developing a new type of computer software. The company wanted to know if their software could run smoothly on multiple operating systems. So, I created a test plan that included running the software on different operating systems to see if there were any issues.”

What is your experience with using software testing tools?

This question can help the interviewer determine your experience level with testing software and how you apply that knowledge to a job. Use examples from your past work experience to highlight your skills in using software testing tools, such as automated testing tools or test management tools.

For example, I used Selenium WebDriver for functional testing of web applications and Appium for mobile application testing. These two tools helped me complete many tasks within my department, including creating new tests and monitoring existing ones.”

Provide an example of a time when you identified a flaw in a product’s design and suggested a solution.

Testing technicians often have the opportunity to identify flaws in a product’s design and suggest improvements. This question allows you to demonstrate your problem-solving skills, communication abilities and critical thinking skills.

Example: “In my previous role as a testing technician, I noticed that one of our products was having issues with its battery life. After conducting some research, I discovered that the company had used an outdated type of battery for this particular product. I presented my findings to my supervisor, who then brought it to the attention of upper management. The company decided to replace the batteries on all units of that product line.”

If a product you were testing started to malfunction, how would you react?

This question can help interviewers understand how you react to unexpected situations. When answering, it can be helpful to describe a specific time when you encountered a malfunctioning product and what steps you took to resolve the issue.

Example: “In my previous role as a testing technician, I was working on a project that required me to test a new software program for a company. After several hours of testing, the software began to freeze up and would not respond to any commands. At first, I thought it might have been an issue with the computer itself, so I restarted it and tried again. However, the same thing happened. I decided to try one more time before calling my supervisor. Luckily, after the third attempt, the software worked properly.”

What would you do if you noticed another employee was intentionally falsifying test results?

This question is designed to assess your integrity and commitment to the company’s values. It also helps employers determine whether you would report any unethical behavior to management or HR. When answering this question, it can be helpful to mention that you would want to ensure the safety of all employees and customers by reporting the incident to a manager or supervisor as soon as possible.

Example: “I would first try to speak with the employee in private about my concerns. If they were uncooperative, I would immediately tell a manager or supervisor so they could address the situation. In addition to ensuring the accuracy of test results, I would also want to make sure no one was putting themselves or others at risk.”

How well do you understand the technical aspects of the products you test?

Testing technicians need to understand the technical aspects of the products they test. This question helps employers determine if you have a strong background in technology and can apply your knowledge to testing products. When answering this question, explain how much experience you have with different types of technology.

Example: “I’ve been working as a testing technician for five years now, so I have quite a bit of experience with different types of technology. In my previous role, I tested software applications, mobile apps and hardware devices. I also worked on projects that involved both software and hardware components. These experiences helped me learn more about the technical aspects of these products.”

Do you have any experience working with industrial equipment?

This question can help the interviewer determine if you have any experience working with testing equipment that is used in industrial settings. If you do, share your experience and how it helped you develop skills that are relevant to this role. If you don’t have experience working with industrial equipment, you can talk about other types of testing equipment you’ve worked with.

Example: “I haven’t had the opportunity to work with industrial equipment before, but I am familiar with some of the common types of testing equipment used in manufacturing facilities. For example, I worked as a quality assurance technician for a software company where we tested new products using different types of software testing equipment. This experience has given me an understanding of what to expect when working with industrial equipment.”

When testing software, what is the difference between a functional test and a non-functional test?

This question is a great way to test your knowledge of software testing. It also shows the interviewer that you understand how important it is to know the difference between these two types of tests and when to use each one. Your answer should include an example of when you used both functional and non-functional testing in your previous role.

Example: “Functional testing is when you check if the application works as expected, while non-functional testing checks for other aspects like performance, usability and scalability. In my last job, I was tasked with creating automated functional tests for our website’s search function. After running through several searches, I realized that the website wasn’t performing well on mobile devices. So, I ran a non-functional test to see where the problem was. Once I found the issue, I fixed it so users could easily find what they were looking for.”

We want to ensure our products are compatible with other companies’ products. What is the best strategy for doing so?

This question is a great way to determine how the candidate will approach testing products for compatibility. It also shows that you are looking for someone who can work with other companies and their products.

Example: “I would first make sure all of our products were compatible with each other, then I would test them against the competitor’s product. This ensures we have done everything we can to ensure compatibility before sending it out into the world. If there are any issues, I would contact the company immediately so they could fix the issue as soon as possible.”

Describe your process for documenting test results.

Interviewers may ask this question to understand how you organize your work and the level of detail you use when documenting test results. Use examples from past experiences to explain how you document information, including details about the tests you run and the data you collect.

Example: “I always make sure to thoroughly document my test results so that I can refer back to them later if needed. In my last role, I used a spreadsheet program to record all of my testing data, including the date and time of each test, the type of test I ran and the data I collected during each step of the process. I also documented any issues or concerns I had with the test results so that I could share these notes with other technicians.”

What makes you stand out from other candidates for this position?

Employers ask this question to learn more about your qualifications and how you can contribute to their company. Before your interview, make a list of all the skills and experiences that relate to this position. Use these skills and experiences to answer this question by explaining what makes you unique from other candidates.

Example: “I have five years of experience as a testing technician, which is more than most people applying for this role. I also have extensive knowledge of various software programs used in this industry, including QAQC and TestTrack. These skills make me an excellent candidate because they show my ability to adapt to new technology and perform well in a fast-paced environment.”

Which testing method do you prefer: black box, white box or gray box?

This question is a test of your knowledge about testing methods. It also allows the interviewer to see how you apply that knowledge in real-world situations. Your answer should show that you understand each method and can use them effectively.

Example: “I prefer gray box testing because it’s the most effective way to find defects in software. I like using this method because it gives me an overall view of the system, which helps me identify problems with the user interface or business logic. Black box testing is good for finding bugs in the code, but it doesn’t allow testers to look at the bigger picture. White box testing is useful when there are issues with the database, but I don’t have much experience with it.”

What do you think is the most important aspect of quality control?

This question is an opportunity to show your interviewer that you understand the importance of quality control in testing technician jobs. Use examples from your experience to explain what you think is most important about quality control and how it impacts a company’s overall success.

Example: “I believe the most important aspect of quality control is ensuring that all test results are accurate. If we don’t have accurate data, then our entire testing process can be compromised. In my last role, I was responsible for making sure that every piece of equipment used during testing was calibrated properly. This included calibrating scales, thermometers and other instruments used to collect data. By performing these checks regularly, I helped ensure that the data collected by testers was accurate.”

How often should you test a product for quality control?

This question can help the interviewer determine your knowledge of quality control testing. Use examples from previous experience to show that you know how often a product should be tested for quality control and what factors influence this decision.

Example: “Quality control is an important part of my job, so I test products as soon as they arrive at the lab. In my last role, we had a set schedule for when each product was due for testing. For example, we would test our electronics twice before shipping them out to ensure that they were in good condition. We also performed random tests throughout the production process to make sure that there weren’t any issues with the products.”

There is a discrepancy between the product’s performance in the lab and its performance in the field. What is your hypothesis?

This question is a great way to test your problem-solving skills and ability to think critically. When answering this question, it can be helpful to provide an example of how you would approach the situation in real life.

Example: “If there was a discrepancy between the lab performance and field performance, I would first look at the testing environment. If everything looks good, then I would move on to the product itself. I would check for any changes that may have been made since the last time the product was tested. For instance, if the product had changed color or texture, I would retest it to ensure that the change didn’t affect its performance.”
