50 Interview Questions About Quality Assurance With Answers

The document that describes, the user action and system response, for a particular functionality is known as USE case. It includes revision history, table of contents, flow of events, cover page, special requirements, pre-conditions and post-conditions. The testing of all the branches of the code, which is tested once, is known as branch testing.

Quality assurance focuses on how you maintain quality and prevent issues where Quality Control focuses on identifying problems with the product or service. If the developer is the chef making a meal, the QA Engineer is the FDA who ensures the food is up to regulatory standards. This ensures a better overall experience for the end user—and qa engineer strengths and weaknesses that’s something everyone can agree is a worthwhile goal. Let’s summarize some of the questions and add a few more divided into specific types. This question assesses the candidate’s problem-solving skills in the context of automation. This question aims to gauge the candidate’s expertise in testing web applications specifically.

What are the contents of test plans and test cases?

Quality assurance is all about making sure everything is up to the highest standard. The interviewer will want to know how you’ll go about testing new features or products, both to make sure they’re up to spec and that the user experience is as smooth as possible. Your answer should include the various methods you use to uncover potential problems and the steps you take to ensure that those issues are addressed.

• To answer this question, explain the process you use to decide which projects or tasks are most important and should be completed first.
• 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.
• Clear and concise documentation helps in ensuring that everyone understands the quality goals and their roles in achieving them.
• I covered topics such as test case design, defect management, and automation tools.

A real-life example is when the QA team tests a mobile banking app pre-release to make sure that it works well on both the front end and back end. They check that the user can log in, view account balances, transfer funds, and make payments on the front end, while on the back end, they test the communication between code modules. Bug leakage is something, when the bug is discovered by the end users or customer, and not detected by the testing team while testing the software. Interviewers ask this question to gauge your familiarity and experience with this aspect of quality assurance. Especially when interviewing for a QA lead job, you’ll need to display your variety of knowledge. Verification and validation both fall into the “quality control” category, but there are four widely regarded methods in use today.

Can you provide an example of how you implemented a new quality assurance process?

In a previous role, we transitioned to a microservices architecture, which required a new approach to quality assurance. Adapting our QA approach ensured that we maintained high-quality standards during the transition. In a previous role, we encountered a recurring issue with software performance. We developed a corrective action plan that included refactoring the code, enhancing performance testing, and implementing monitoring tools. By executing this plan, we significantly improved software performance and reduced customer complaints.

The platform is continually updated to keep up with the latest trends, and experienced testers can even have a look to keep their knowledge up-to-date. API testing is key because almost every application type is heavily reliant on APIs. The UI and API are interlaced, making it even more critical to understand how data and logic processes from one layer to the other. Investment in developers/automation engineers and tools for test automation, CI, test management and defect tracking.

What Are The Differences Between Quality Assurance & Quality Control?

Quality assurance engineers (or QA Engineers) provide support to software development teams when it comes to application creation, application testing, implementation, and troubleshooting. That means that they are involved in the development process from beginning to end. Quality assurance is often seen as a “gatekeeper” role, and it can be difficult to explain why a product needs to be improved. If you’re interviewing for a QA position, it’s important to be prepared with the right answers to common interview questions. Knowing what questions to expect can help you come up with better responses and show off your skills more effectively.

For instance, if you’ll mainly be working with web services or web APIs, you might mention Selenium testing tools. Automation plays a big role in software testing in tandem with the continued importance of manual testing, as well. The bug release step allows a QA engineer to find high priority and small issues alike.

QA (Quality Assurance) Interview Questions and Answers

Start by explaining the basics of regression testing, such as what it is and why it’s important. Then, provide examples of how you have applied this knowledge in your previous roles. Finally, discuss any tools or techniques you use to make sure that all tests are properly performed and documented. Quality assurance is all about finding and fixing bugs in a product before it is released to the public.

As with behavioral questions, which focus on the past, you can use the STAR method to walk interviewers through your proposed strategies. Behavioral questions are an opportunity to explore your professional background and describe how you’ve handled workplace situations. You’ll use the STAR method (Situation, Tasks, Actions, Results) to answer behavioral questions with detailed, compelling stories about your past successes.

This sample of Quality Assurance (QA) Engineer interview questions is optimized to help you identify skilled candidates for your software Quality assurance position. From the example, we can see that the exit criteria need to be strict, yet reasonable. Both verification and validation are vital in the QA process as both will allow for recognizing defects in a different manner. Verification identifies defects in the specification documentation, while validation finds defects in the software implementation.

Using an RTM, we can confirm 100 percent test coverage of the business and technical requirements, as well as have a clear overview of defects and execution status. It undoubtedly highlights any missing requirements and/or discrepancies in the documentation. Visual testing can be performed manually, where the tester checks the application visually for inconsistencies. The point of data-driven testing is not hard-coding and limiting tests to a single input value. 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.

What are the tools used by a tester while testing?

For instance, I use Agile for iterative and incremental development projects and Six Sigma for process improvement initiatives. Though automation is key, manual testing remains a necessary part of the process, too. Draw upon your previous experience or review things like implementing QA in a CI/CD pipeline to best prepare yourself. All job interviews ask basic questions to get a sense of a person’s work ethic, personality, and experience. The same goes for any interview for QA jobs, QA leads, or other testers in the software industry. As an interviewee, I would try to add as much detail as possible when answering technical questions.
