Daffodil Software Test Engineer Interview: Rounds, Questions and Preparation

What the job involves

Test Engineers in Indian IT services validate software applications by writing and executing test cases, identifying defects, and ensuring product quality before release. They work closely with developers and business analysts, often on multiple client projects, and use both manual and basic automation testing tools. Day to day tasks include reviewing requirements, preparing test data, logging bugs in tools like JIRA, and participating in daily stand-ups.

Role and Technical Knowledge

1. 1

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

   Explain that verification checks if the product is built correctly (reviews, inspections) while validation checks if the correct product is built (actual testing). Give a simple example like reviewing a design document versus executing test cases.

2. 2

   Can you explain the defect life cycle with the states a bug goes through?

   Cover states like New, Assigned, Open, Fixed, Retest, Verified, Closed, and Reopened. Mention that a tester logs a defect, the lead assigns it, the developer fixes it, and the tester retests before closing.

3. 3

   What are the different levels of testing you have studied?

   List unit, integration, system, and acceptance testing. Briefly state the purpose of each and who typically performs them in a project.

4. 4

   How do you decide when to stop testing?

   Mention criteria like test case execution percentage, defect closure rate, risk analysis, and deadlines. Show awareness that testing ends based on coverage and business priorities, not just time.

Practical Scenarios and Tools

1. 5

   You are asked to test a login page. What test cases will you write?

   Cover positive cases (valid credentials), negative cases (wrong password, blank fields), boundary cases (max length), and UI checks. Mention security aspects like password masking and SQL injection attempts.

2. 6

   How would you test an e-commerce checkout process?

   Describe testing the cart, applying coupons, payment gateway integration, order confirmation, and email notifications. Include both functional and non-functional aspects like performance under load.

3. 7

   What is the difference between a test plan, test strategy, and test case?

   Explain that a test plan is a document detailing scope, approach, and schedule for a project; a test strategy is a high-level document across projects; a test case is a step-by-step procedure with expected results.

4. 8

   How do you handle a situation where a developer marks your bug as 'Not Reproducible'?

   Say you would provide detailed steps, screenshots, logs, and environment details. If still unresolved, you would involve the test lead and try to reproduce on a similar environment.

Behavioural and Situational Questions

1. 9

   Tell me about a time you found a critical bug under a tight deadline. How did you handle it?

   Use the STAR method: describe the situation, your task, the action you took (like prioritizing and communicating), and the result (bug fixed before release). Highlight teamwork and communication.

2. 10

   How do you prioritize your testing when you have limited time?

   Explain that you focus on high-risk, high-impact functionalities first, use risk-based testing, and communicate with the lead about what can be deferred. Show that you understand business priorities.

3. 11

   Describe a time you disagreed with a teammate. How did you resolve it?

   Pick a non-conflict example where you listened, presented data or facts, and reached a compromise. Emphasize respect and focus on the project goal.

4. 12

   Why do you want to work as a Test Engineer in a services company?

   Talk about exposure to different domains and clients, structured training, and the importance of quality. Show enthusiasm for learning and adapting to new tools and technologies.

HR and Company Fit

1. 13

   What do you know about our company and why do you want to join us?

   Research the company's services, clients, and work culture. Mention specific aspects like their focus on emerging technologies or their training program that attracts you.

2. 14

   Are you willing to relocate or work in different shifts?

   Be honest but flexible. If you are open, say yes and explain that you see it as an opportunity to learn. If not, state your constraints clearly and professionally.

3. 15

   What are your salary expectations?

   For a fresher, say you are open to the company's standard package as per industry norms. You can add that you are more focused on learning and growth at this stage.

4. 16

   Where do you see yourself in the next three years?

   Show a realistic path: starting as a test engineer, gaining expertise in automation and domain knowledge, and eventually taking on more responsibility like leading a small module or team.
