As you begin your prep to crack your next tech interview, here are some software test engineer interview questions and answers to help you get started:
Software testing can be divided into three methods:
If you’re a fresher preparing for an interview, this is an important one in the list of test engineer interview questions because it tests your basics.

The four primary levels of testing (in the order in which they are executed):
A set of conditions or variables based on which a tester determines whether a system under test satisfies the requirements and works correctly is known as a test case.
The process where a defect goes through the different stages during its life cycle is called a defect life cycle. It begins when the defect is detected and ends when the defect is closed, and it’s ensured that it won’t be reproduced.
The defect life cycle varies from company to company and even project to project because it’s based on a number of factors. These are — organization policy, software development model being used, project timelines, and so on.
All freshers going in for the interview can expect such software test engineer interview questions. So ensure that you prepare accordingly since they cover your basics.
Yes, it is. Testing is only done when the build and execution phases are complete. As the sooner you catch a defect, the earlier you can resolve it making it a more cost-effective method. For instance, when you fix a defect in maintenance, it becomes ten times costlier than it would have been during execution.
Regression testing: The type of software testing that confirms that a recent code change hasn’t negatively impacted the existing features is called regression testing.
Confirmation testing: Whenever a test fails due to some defect, this defect gets reported, and when the new version of this software is submitted after getting fixed, it is known as confirmation testing or re-testing.
Boundary Value Analysis or BVA is a black box test design technique. It is applied whenever the test engineer needs to see if there are any bugs present on the boundary of the input domain.
When applying for mid-level roles, you can expect such test engineer interview questions.
When working on a project, an estimate is made based on the following factors:
Mostly, black box test cases are written first, followed by the white box test cases. This is because when black box test cases are written, they need the required document and design or project plan. These documents are easily available in the initial phase of the project.
But white box test cases can’t be started in the initial phase because they need more architectural clarity that isn’t available in the beginning. So usually, white box test cases are written after black box test cases.
The basic components of the defect report format are:
So if you’re going looking for intermediate-level questions, do keep the test engineer interview questions given above in mind and prepare more such questions.
These five questions are advanced-level senior test engineer interview questions, and you should expect to face such questions as you advance up the ladder.
A workbench is a way of documenting how a particular needs to be performed. It is mostly known as phases, steps, and tasks. Every workbench has five tasks, and they are:
For rollout, the strategies that need to be followed are:
With the help of the TakeScreenshot function, you can take a screenshot. Using the getScreenshotAs() method, you can save any screenshot that you take. For instance,
File scrFile = ((TakeScreenshot)driver).getScreenshotAs(outputType.FILE);
If you’re looking for advanced-level questions, you can focus on such test engineer interview questions.
When the frame name and frame id aren’t there, one can use frame by index. For instance, if there are three frames in a web page and none of them have a frame name and frame id, then you select those frames with the help of the frame index attribute (zero-based) .
All the frames have an index number, just like the first frame will be at index “0”, the second will be at index “1,” and the third will be at index “2”.
If you want to skip a particular test or a code, you can just set the ‘enabled’ parameter in the test annotation to false.
@Test(enabled = false)
Learning the answers to these test engineer interview questions for senior and fresher software engineers will help you prepare for your tech interview.
Now that you have a good idea of what sort of questions you can expect at the different levels, here are some more sample software test engineer interview questions for practice:
Q1. Explain verification and validation in software testing.
Q2. What is meant by defect cascading?
Q3. How should one go about creating a test script?
Q4. How can you use Selenium WebDriver to find broken links on a page?
Q5. What input is needed from the end-user to begin proper testing?
Q6. What do you do when certain documents for a given test are missing?
Q7. Differentiate between smoke testing and sanity testing.
Q8. What are the challenges of software testing?
Q9. In software testing, what are test closure tasks?
Q10. What is the difference between system testing and integration testing?
The right test engineer interview questions can really change the game for you as they help you develop the right mindset for these interviews. Your competence, confidence, and patience as a test engineer must be reflected in your responses to these test engineer interview questions. So prepare diligently and thoroughly.
Q1. What are some important test engineer interview questions?
Some common test engineer interview questions are: What troubleshooting systems do you use to finalize your testing procedures? How do you stay updated with product and engineering knowledge? What information is vital for creating testing procedures for a product?
Q2. How to prepare for test engineer interview questions?
Research the company you’re going to interview for and practice answering questions. Be sure of your answers since, as a test engineer, your confidence and decision-making skills are tested.
Q3. How many rounds are there in a test engineer interview?
There are three rounds in a test engineer interview. The first is the technical interview, followed by an interview with the manager (non-technical), and finally, salary negotiations with HR.
Q4. What technical skills do test engineers need to have?
Some important technical skills that a test engineer needs are: Agile Testing, Automation Testing, Software Development Life Cycle (SDLC), Technologies in Web and Mobile, among others.
Q5. Do test engineers need to know how to code when preparing for test engineer interview questions?
Coding is not a prerequisite for becoming a test engineer because they aren’t exactly responsible for doing that. They just need to ensure that the required output is being produced.
