Top 10 Technical QA Interview Questions & Answers 2024

Thread testing validates the critical functional capabilities of a specific task called a thread. The testing team performs thread testing at the onset of integration testing. We’ve got you covered with this comprehensive set of QA interview questions that will help you reduce interview anxiety. Interviewers ask this question to gauge your familiarity and experience with this aspect of quality assurance. They want to know how you approach QA challenges, such as tight deadlines or fixing bugs during the testing process, and the actions you take to succeed. We’ve grouped the following interview questions into three categories—behavioral, situational, and testing-related questions—so that you can prepare for a range of questions.

Data driven testing is an automation testing framework, which tests the different input values on the AUT. The testers must possess coding skills in order to implement white box testing so that they can work with internal code. Now, let’s cover questions you might hear in a quality assurance interview for experienced professionals. Load testing is the process of testing an application under a significant but anticipated load. Here, the load is basically the volume of users, messages, requests, data, etc.

Understanding the bug life cycle is essential for a QA Test Engineer, as it demonstrates your ability to effectively identify, track, and resolve defects within a software system. During sprint planning meetings, I collaborated with developers, product owners, and other team members to understand the scope of work and define testable acceptance criteria. This allowed me to create comprehensive test plans and cases before the development phase began. During the development cycle, I performed continuous testing on new features and bug fixes as they were completed, providing prompt feedback to the developers.

His transition from Selenium to Cypress at DataSite demonstrates his adaptability and forward-thinking approach. At CNBC, Ibrahim was pivotal in enhancing the release process, ensuring stable and bug-free delivery. That is where we apply an exit criteria document, which lists the conditions that have to be met prior to the release of the product.

Explain end to end testing in your own words. Compare End to End Testing vs Integration Testing

QA engineers play a critical role in ensuring the quality of software products. They work with developers and product managers to design and execute tests, track defects, and report on the quality of the product. Testing software is all about ensuring quality and functionality, and regression testing is a critical component of that process. When updates, bug fixes, or new features are added to the software, there’s a chance that something that previously worked well might now be broken.

These technical QA interview questions will assist you in gaining a thorough knowledge of quality assurance concepts. You can pick the concepts from here and learn them in-depth via online resources. The programmer who tests the modules also performs unit testing, and immediately fixes any discovered bugs. Adhoc testing is a non-formal process of testing software without any planning, requirements, specifications, or documentation. Most entry-level professionals can conduct adhoc testing — you don’t need an experienced testing engineer.

Explain the steps for Bug Cycle?

Measuring the effectiveness of testing efforts is a vital aspect of ensuring software quality. Interviewers want to know how you gauge the success of your testing strategies to determine if you’re capable of identifying areas of improvement and adapting your approach accordingly. This demonstrates your analytical thinking, attention to detail, and commitment to delivering reliable and well-tested software. Once the testing phase is qa engineer strengths and weaknesses complete, I analyze the results and verify that all critical issues have been addressed and resolved. Additionally, I collaborate closely with the development team to confirm that any remaining known issues are either minor or have an acceptable workaround. It’s essential to maintain open lines of communication with stakeholders throughout this process to keep them informed about the product’s status and readiness for release.

The point of this question is to see if they know how to choose the right metrics depending on the specific tests and goals and what factors they take into consideration. Questions like this can show whether a candidate can think on their feet and outside the box, which are great traits for a QA engineer to have. Here, your candidate will most likely explain how they have handled busy times in the past. But you’re also checking for evidence of teamwork, collaboration, problem-solving skills, and more. A candidate who says “yes” to this question is more likely to be a team player and be motivated to do whatever it takes to overcome obstacles. A good way to evaluate this is to use a Culture Add test, where you can compare your candidates’ values and behaviors with those of your organization.

Problem-Solving and Critical Thinking

There are a few reasons why an interviewer might ask a QA Engineer about their thoughts on regression testing. First, it is a way to gauge the QA Engineer’s level of experience and knowledge on the subject. Second, it allows the interviewer to get a sense of the QA Engineer’s testing methodology and approach. Finally, it gives the interviewer an opportunity to see how the QA Engineer would handle a real-world testing scenario. There are a few reasons why an interviewer might ask a QA Engineer about their responsibilities in their current role.

Your experience with test automation tools is essential because these tools are a critical part of a QA Test Engineer’s toolkit. They help streamline the testing process, making it faster, more consistent, and less error-prone. On the other hand, white box testing involves examining the internal workings of an application, such as code structure, logic, and algorithms. Testers who perform white box testing have access to the source code and use their knowledge of programming languages and coding practices to design test cases.

Integration testing looks at how individual integrated components, from the API to UI, work. Testers manually perform actions  (e.g., open browser, set texts) to interact with the application-under-test. Tests are written in text editors on Xray, test management tools or spreadsheets. The point of data-driven testing is not hard-coding and limiting tests to a single input value.

• As a senior QA engineer, you need to be familiar with the latest programming languages and tools.
• Exploratory testing is typically performed by experienced testers who use their domain knowledge, intuition, and creativity to identify defects in the software.
• The interviewer may ask you this question to understand how you apply your skills and experience to test for usability.
• The goal of SQC is to perform testing activities on the final product to validate that the product that was developed is in accordance with the needs and expectations of the customer.

Instead, you’ll be parameterizing and using global variables for your test to read directly from databases, spreadsheets, or XML files. BDD is also a development approach, but drives the design of software via an end-user’s perspective. In terms of environment selection, set up the hardware and software that best reflect the real-life environment in which the application is used. Teams have the option to choose between cloud environments and physical devices. The decision between the two falls on the nature of an application-under-test and how end-users are accessing it. Together, testers and developers will need to fully understand and input on how business requirements are feasible or not for implementation.

What is performance testing?

It is important for the interviewer to know how the QA Engineer would handle this type of situation because it can give them insight into the QA Engineer’s work ethic and ability to meet deadlines. I often use Postman to create collections of test cases, which allows me to organize and manage tests efficiently. Additionally, I leverage its scripting capabilities to automate repetitive tasks and validate responses using JavaScript. For more complex scenarios or when working with SOAP services, I turn to SoapUI, where I can import WSDL files and generate test suites quickly.
