Interviewer: How do you prioritize testing tasks when testing time is limited?
Candidate: I prioritize testing tasks based on the criticality of the feature or module and the potential impact on the end-user. I also work with the development team to identify any high-risk areas that require immediate testing.
Interviewer: Can you describe a time when you had to manage competing priorities and how you handled it?
Candidate: In my previous role, I had to manage competing priorities during a crunch time for delivery. I had multiple testing cycles occurring simultaneously, and I used a prioritization system to ensure that the most critical features were tested first. I also worked very closely with the development team to ensure that any defects were addressed quickly.
Interviewer: Finally, can you describe what you believe to be the most important trait for a successful Quality Assurance Engineer?
Candidate: I believe that the most important trait for a successful Quality Assurance Engineer is a passion for quality. This means having a strong attention to detail and making sure that every aspect of the product is tested thoroughly. It also means being willing to go the extra mile to ensure that the product meets or exceeds expectations.
1. Scenario: Imagine that you are testing a mobile app for a car rental company. A user has reported that they were unable to complete a reservation due to an error message. How would you go about reproducing the issue and testing it to ensure that it is resolved?
Candidate Answer: First, I would attempt to reproduce the issue by following the same steps that the user reported. This includes identifying the specific page and filling out the required information for the reservation. Once I am able to reproduce the issue, I would take a screenshot of the error message and gather any relevant details such as the user's device and software version. I would then log the issue into a bug tracking system and assign it to the appropriate developer for resolution. After the issue is resolved, I would perform regression testing to ensure that the fix did not cause any other issues.
2. Scenario: Assume that you are testing a web application that allows users to purchase products. The stakeholders have requested that you provide them with the average time it takes to complete a purchase. How would you collect and analyze this data?
Candidate Answer: To collect the data, I would use a tool such as Google Analytics to track the user's behavior on the website. Specifically, I would track the time between when the user selects the product and when they complete the purchase. I would then export this data into an excel spreadsheet and calculate the average time it takes to complete a purchase. I would also provide additional information such as the time it takes for users to abandon their cart and any other relevant metrics.
3. Scenario: You have been assigned to test a new feature for a social media application. The feature allows users to upload and share videos with other users. What specific types of testing would you perform to ensure the feature is stable and user-friendly?
Candidate Answer: Firstly, I would perform functional testing to ensure that the feature works as intended. This includes testing features such as video upload, sharing, and playback. I would also perform boundary testing to ensure the feature can handle various file types and sizes. Secondly, I would perform compatibility testing to ensure that the feature works on various devices and browsers. Finally, I would perform user acceptance testing, where a select group of users would test the feature and provide feedback on its user-friendliness.
4. Scenario: You are testing a new billing system for a financial services organization. It is critical that the system is accurate to ensure that customer payments are processed correctly. What types of testing would you perform to ensure the accuracy of the system?
Candidate Answer: I would perform both automated and manual testing to ensure the accuracy of the system. For automated testing, I would use a tool such as Selenium to test the system's functionality and perform data validation checks. For manual testing, I would simulate various user scenarios and verify that the system calculates payments correctly. I would also perform thorough data validation checks to ensure that input is accepted correctly and output is correct. Additionally, I would perform regression testing to ensure that any changes do not cause any defects in the billing system.
5. Scenario: You are testing a mobile app for a new restaurant. One of the features allows users to place a reservation. What types of testing would you perform to ensure the feature is working as expected?
Candidate Answer: Firstly, I would perform functional testing to ensure that the feature works as intended. This includes testing features such as reservation form functionality, reservation confirmations, and email notifications. Secondly, I would perform load and performance testing to ensure that the feature can handle various user traffic scenarios. This includes simulating a heavy load of reservations being placed at the same time. Finally, I would perform security testing to ensure that customer details (such as name and credit card information) are securely handled and not vulnerable to any malicious activity.
