QA Interview Questions & Answers – Part 3

qa interview answers questions

1. Are you better working in a team or working alone?

Answer: I am a team player. I get along with team members very well. As far as the working is concerned, I can be equally productive in team or working alone.

(Caution: Never say, I like working alone. This could lead you to not getting a job as they are always looking for people who can get along with other people.)

2. Do you have any situations in the past where you have some arguments with your team members?

Answer: No. I never had that type of situation wherever I have worked.

(Even if you had one, it’s a good idea to say “No”. This could be a red flag, which might stop you from getting the job)

3. What do you like about a Manager? And what don’t you like?

Answer: The best thing I like about a Manager is that the Manager should be able to coordinate with the other teams so that we can get the updated documents, for example, updated requirements documents right away. A Manager who can efficiently in distributes the work to the team, without being biased and easily accessible and protective to his team for the right cause. As far as “what I don’t like” is concerned, I don’t like a manager who keeps coming to desk 10 times a day to check my work even if it is just a regular work. Once the responsibility is given, the team member should be trusted and let his work done.

4. Where do you see yourself in another 5 years?

Answer: I see myself a QA Lead in another 5 years.

(You can also say “QA Manager”, but since the QA Manager is taking your interview most of the time, they sometimes feel challenged. Therefore, it might be a good idea to limit you to QA Lead)

5. Why are you in QA?

Answer: I am in QA because I like this job.

6. Why do you like this job?

Answer: I like this job, because it is process oriented. Meaning that I get an opportunity to work from analyzing the requirement documents to writing test plans, test cases, testing the application, logging defects, retesting, preparing reports and finally testing in production as well. Therefore, I am involved from the very beginning to the end of the software development life cycle (SDLC) process. I like this.

Another reason is I like to find defects. I enjoy logging defects. The more defects I find, the happier I am.

7. How do you determine what to test in an application?

Answer: First of all we have the test cases (or test scripts) that are written based on the requirement document. This pretty much covers what functionalities to test. Therefore, looking at the test cases tells us what to test in the application.

8. If you have no documentation about the product, how do you test an application? Describe the process.

Answer: Well, this is a situation where I have come across several times. Some of the companies in my previous projects did not have any documents. In this case, I went to the Business Analyst and sometimes to developers to find out how exactly the functionalities work, how to navigate from one page to another page and so on. After getting a clear vision, I write test cases based on the conversation (which is a step by step procedure to test an application) and get ready for testing.

9. What do you do once you find a defect?

Answer : Once you find a defect, this is what we need to do:

Recreate the Defect: Once you find a defect, we must try to recreate (meaning that we should be able to reproduce it) at least 3 times so that we are sure that it is a defect. Sometimes, once we find it log it without recreating, may put us in a false situation (because sometimes the application does not behave in the same way). Therefore, it is important to recreate the same defect several times.

  1. Attach the Screen Shot (supporting document): Once we confirm that it is a defect, and then it is a good idea to attach supporting documents when we log (write) a defect. For example, screen shot, requirement document etc. For instance, let us say that instead of “Continue” button on a page, there is a typo “Contiinuee”. Now, we will make a screen shot of this page (To make screen shot, press “Print Screen” button on the keyboard, and open a Word document, and Click Edit on the Word document and “Past” it. You will see the screen now) Now, a tester needs to write defects in easy and clear language to make all the developers to understand easily.
  2. Log the Defect: Now, the next step is, we need to log it. Depending on the company what kind of tools they are using (for example, some companies use TestDirector to log defects, some companies use Rational ClearQuest, some use PVC Tracker and so on). If the company is small and cannot afford these expensive tools, then they may simply use Excel sheet to log defects. We log the defect.

What are the basic elements you put in a defect?

Answer: Basic elements we put in a defect are: SEVERITY, PRIORITY, CREATED BY, VERSION NO, HEADER, DESCRIPTION OF THE DEFECT where we write how to recreate a defect, in what module the defect is found, Status, and so on.

10. What is the biggest bug you have ever found?

Answer: Well, there are many big defects I have found in various projects. For example, in the last project, on a page, there was a button called “More Information”. Once the user clicked that button, the system would open a new window (pop up).

We could close the new window in 3 ways:

-By clicking X at the top right corner of the page

-By clicking “Close” button on the page

-By pressing combination keys (Alt+F4) on the key board

Although the combination key (Alt+F4) was not mentioned in the test case, I just wanted to try how the application reacts when Alt+F4 is pressed. Then I pressed Alt+F4. The result was a disaster-the application crashed (broke). The application disappeared from the computer monitor. Since it was the last day of testing for us, it brought chaos in our Managers, Leads and the whole teams. Finally, the developers disabled Alt+F4 as a temporary solution and the application went into production.

11. How do you make sure that it is quality software?

Answer: There is a certain process how the quality of software is guaranteed (ensured). If is defined by the ‘exit criteria’. (What it means is, a QA Manager writes a document called Test Strategy. This Test Strategy defines the ‘exit criteria’.) Exit Criteria gives the measurement, for example, in order to confirm the quality, how many critical defects, high defects, medium defect and low defect are acceptable? These are all defined in the exit criteria. (Normally in practice, for a quality software, there should no critical defects (0 critical), no high defect (0 high), no medium defect (0 medium) and may be 1 low defect)

12. As a QA Tester, can you tell me the situation when you felt the most proud of it?

Answer: When I find the defect that normally others don’t find, then I feel very proud. For example, there were situations where I found bugs that crashed the whole system at the end of testing phase. I tried the scenarios where the scenarios were NOT mentioned in the test cases. For example, we can close the windows by clicking X on the page, with “Close” button and so on. But there is another way that you can close the window, by pressing Alt+F4 on the keyboard. Not many testers test this scenario. I have done this in my last two projects. Both the time, the application crashed which became a big issue. I felt proud.

13. What made you to choose testing career?

Answer: I am a very detailed oriented person and I like process-oriented job. The way QA process works is just the kind of work I like. For example, analyzing requirement documents, attending walk-through meetings, writing test plans, writing test cases, executing the test cases (or running the test cases) testing the application, logging defects, retesting them and so on. I think I really like the process and that’s why I chose this career.

14. When should testing start in a project? Why?

Answer: We should start testing as soon as the following things are ready:

-Test Data are ready

-Build (all the developers have coded their code and merged them together)

-Test Environment (servers, network etc) is set up and ready

-When the manager asks us to go ahead and start testing.

15. Let us say you have a web application to test. How do you go about testing it? What is the process?

Answer: First of all, I will look at the requirement documents (or design document in some companies). The requirement document will tell us what the functionalities in the application (software) are. Once I analyze the requirement documents (one module=one requirement document). After that, I will write test plans for each module (one module =one test plan). Then after the test plan is complete, I will write test cases (One module can have hundreds, even thousands test cases). Once the test cases are ready and the application is ready (or once the build is ready), then I will start testing. Before I start testing, however, I will make sure the test environments, test data and defect logging tools are in place. This is how I will go about testing an application.
