True Elements QA Engineer Interview: Rounds, Questions and Preparation

What the job involves

A QA Engineer at Indian unicorns and high-growth startups like True Elements ensures that products meet quality standards before release.

You also participate in release planning and regression testing to maintain product reliability.

Role and Technical Knowledge

1. 1

   What is the difference between verification and validation in software testing?

   Explain that verification checks if we are building the product right (reviews, inspections), while validation checks if we built the right product (actual testing).

2. 2

   How would you test a login page of a food delivery app like True Elements?

   Cover positive and negative scenarios: valid credentials, invalid password, empty fields, SQL injection, password masking, and forgot password flow.

3. 3

   What is a test case and what are its key components?

   Mention test case ID, description, preconditions, steps, expected result, actual result, and status. Give a simple example.

   What is regression testing and when do you perform it?

   Explain that regression testing ensures new changes do not break existing functionality. Perform after bug fixes, new features, or code changes.

4. 8

   How do you decide which test cases to automate?

   Consider repetitive, high-risk, data-driven, and stable test cases. Avoid automating tests that change frequently or require manual judgment.

Behavioural and HR

1. 9

   Show growth mindset: moving into automation, leading a small team, or becoming a subject matter expert in testing.

Tools and Automation Basics

   What is the difference between manual and automated testing?

   Manual testing is done by humans, good for exploratory and usability tests. Automated testing uses scripts, good for repetitive and regression tests.

2. 14

   Have you used any test management or bug tracking tool? Explain.

   Mention tools like JIRA, Trello, or TestRail. Describe how you log bugs, track status, and link test cases.

3. 15

   What is API testing and why is it important?

   API testing checks the communication between software components. It is important for early detection of issues and testing without a UI.

4. 16

   Write a simple SQL query to find all users who placed more than 5 orders.
