Check out the top manual testing interview questions for experienced QA engineers. In this post, we’ve added some of the most relevant questions/answers for the senior QA engineers. These would not only remind you the roles/responsibilities of an experienced QA but also help in preparing for a manual testing interview.
Our team put a lot of efforts in choosing and preparing for these QA interview questions. It took us several discussions with the elite members of the testing community to find out the answers in a truly simplified format. Many thanks to them as all of them were readily available to partner with us for this post.
Also, during the meetings, we came across few points that could be key to a successful job interview. We are listing them below so that you can work on them.
- Read about the company and the opportunity.
- Be good at non-vocal skills.
- Show them your confidence, make proper eye contact and stand straight.
- Brace for a great start.
- Dress well.
- Prefer to wear a formal outfit.
- You may even look out for a dress code in the company if they’ve any.
- Neither talk too much nor pretend to be too familiar.
- Be polite while replying.
- Take time to think before answering a question.
- Ask questions.
- Don’t look desperate.
- Be authentic, candid and concise.
- Thank the interviewer in person.
Apart from these manual testing interview questions, you might like to check out the below posts. These offer some of the best technical questionnaires for Senior test engineers.
Also, it’s not late that we’d posted a two part series of Software testing interview questions and answers. So please see through these blog posts, they might be pretty useful for the interview preparation.
Now, it’s time to get into reading the most important manual testing interview questions for experienced testers.
Top Manual Testing Interview Questions for Experienced QA Engineers.
Q-1# What is Requirement Traceability Matrix?
Ans# The Requirements Traceability Matrix (RTM) is a tool that maintains a mapping of the test scenarios with the requirements. That’s how it ensures that the Test Plan covers all the requirements and refers to the latest version of requirements.
Q-2# Explain the difference between Pilot and Beta testing?
Ans# Read the following points to know the difference between Pilot and Beta testing.
1. We do the beta test when the product is about to release to the customer whereas pilot testing takes place in the earlier phase of the development cycle.
2. In the beta test, testing application is given to few users to make sure that application meet the customer requirements and does not contain any showstopper bug. Whereas, in the pilot test, few members of the testing team work at the Customer site to set up the product. They give their feedback also to improve the quality of the end product.
Q-3# Describe how to perform Risk analysis during software testing?
Ans# Risk analysis is the process of identifying the hidden issues that may derail the successful delivery of the application. It also prioritizes the sequence of resolving the identified risks for testing purpose.
Following are some of the risks that are of concern to the QA.
1. New Hardware.
2. New Technology.
3. New Automation Tool.
4. The sequence of code delivery.
5. Availability of test resources for the application.
We prioritize them into three categories which are as follows.
1. High magnitude: Impact of the bug on the other functionality of the application.
2. Medium: it is tolerable in the application but not desirable.
3. Low: it is tolerable. This type of risk has no impact on the company business.
Q-4# Do you know about Silk Test? Explain in your words.
Ans# Here are some facts about the Silk tool.
1. It’s a tool developed for performing the regression and functionality testing of the application.
2. It benefits when we are testing Window based, Java, the web, and the traditional client/server applications.
3. Silk Test help in preparing the test plan and managing them to provide the direct accessing of the database and validation of the field.
Q-5# What is the difference between Master Test Plan and Test Plan?
Ans# The difference between Master Plan and Test Plan can be described using following points.
1. Master Test Plan contains all the test scenarios and risks prone areas of the application. Whereas, Test Plan document contains test cases corresponding to test scenarios.
2. Master Test Plan captures each and every test to be run during the overall development of application whereas test plan describes the scope, approach, resources and schedule of performing the test.
3. MTP includes test scenarios to be executed in all the phases of testing that run during the complete life cycle of the application development. Whereas, a separate Test Plan exists for each phase of testing like Unit, Functional, and System which contains the test cases related to that type only.
4. Only for big projects, we need a Master Test Plan which requires execution in all phases of testing. However, preparing a basic Test Plan is enough for small projects.
Q-6# How do you handle a non-reproducible bug?
Ans# Following bugs lie under the non-reproducible category.
1. Defects observed due to low memory issue.
2. Bugs raised due to address pointing to a memory location that does not exist.
3. The race condition is an error scenario which occurs when the timing of one event impacts another executing in a sequence.
A tester can take the following actions to handle the non-reproducible bugs.
1. Execute test steps that are close to the error description.
2. Evaluate the test environment.
3. Examine and evaluate test execution results.
4. Keeps the resources & time constraints under check.
Q-7# How do you perform Automated Testing in your environment?
Ans# Automation Testing is a process of executing tests automatically. It reduces the human intervention to a great extent. We use different test automation tool like QTP, Selenium, and WinRunner. These tools help in speeding up the testing tasks.
Using the above tools we can create test scripts to verify the application automatically. After completing the test execution, these tools also generate the test reports.
Q-8# What factors make you choose automated testing over manual testing?
Ans# The choice of automated testing over manual testing depends on the following factors.
1. The frequency of execution of a test case.
2. The test case contains repetitive test steps.
3. Time Comparison (time for preparing and running automated script for the first time is much less than manual execution time).
4. Reusability of Automation Script.
5. No frequent change in the execution environment.
6. Availability of automated test reports for every execution.
7. Small releases like service packs which include a minor bug fix. In such cases, regression type of cases is sufficient for validation.
Q-9# How do you define test driver and test stub? Explain using an example.
Ans# The test driver is a piece of code that calls a software component under test. It is useful in testing that follows the bottom-up approach.
Test stub is a dummy program that integrates with an application to complete its functionality. These are relevant for testing that uses the top-down approach.
Let’s take an example.
1. Let’s say there is a scenario to test the interface between modules A and B. We have developed only module-A. Then we can test module-A only if we have real module-B or a dummy module for it. In this case, we call module-B as the Test Stub.
2. Now module-B can’t send or receive data directly from module-A. In such scenario, we’ve to move data from one module to another using some external features called Test Driver.
Q-10# What are the essential qualities of an experienced QA or Test Lead?
Ans# Every QA or Test Lead should have the following qualities.
1. Thorough knowledge of Software testing processes.
2. Ability to accelerate teamwork to increase productivity.
3. Improve coordination between QA and Dev engineers.
4. Provide ideas to refine the QA processes.
5. Ability to conduct RCA meetings and draw conclusions.
6. Excellent written and interpersonal communication skills.
7. Quick learner and able to groom the team members.
