STT GDC India Test Engineer Interview: Rounds, Questions and Preparation

What the job involves

A Test Engineer in Indian IT services validates software applications and systems to ensure they meet functional and non-functional requirements before release. Day to day, you design and execute test cases, log defects, and work with developers and business analysts in Agile teams. At companies like STT GDC India, you may also test data centre management software, infrastructure monitoring tools, or enterprise applications.

Role and Technical Knowledge

1. 1

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

   Verification checks if the product is built correctly (reviews, walkthroughs), while validation checks if the correct product is built (execution). Give a concrete example like reviewing a requirement vs. running a test case.

2. 2

   Explain the defect life cycle with the states a bug goes through.

   Cover New, Assigned, Open, Fixed, Retest, Verified, Closed, and Reopened. Mention who moves the defect between states and why a defect might be deferred or rejected.

3. 3

   What are the key differences between smoke testing and sanity testing?

   Smoke testing checks critical functionalities on a new build to decide if further testing is possible. Sanity testing checks specific functionality after a minor fix. Give a scenario where each is used.

4. 4

   How would you test a login page? List the test cases you would write.

   Cover positive and negative cases: valid credentials, invalid password, empty fields, SQL injection, password masking, forgot password link, and session timeout. Show structured thinking.

Practical Scenarios and Tools

1. 5

   You find a bug but the developer says it is not reproducible. What do you do?

   Explain that you would provide detailed steps, screenshots, logs, environment details, and video evidence. If still not reproducible, you would try different environments and involve the test lead.

2. 6

   How do you decide which test cases to include in a regression suite?

   Base it on criticality, frequency of use, and areas prone to defects. Mention that regression suites should be reviewed and updated regularly, and automated where possible.

3. 7

   Write a SQL query to find duplicate records in a table.

   Use GROUP BY and HAVING COUNT(*) > 1. Explain the query and mention that you might also use ROW_NUMBER() for more complex cases.

4. 8

   What is API testing and how is it different from UI testing?

   API testing tests the business logic layer directly without a GUI, often using tools like Postman. UI testing tests the user interface. Mention that API testing is faster and more stable.

Behavioural and Teamwork
