2. Technical Screening

• Format: 45-minute video call with a senior quality engineer or team lead.
• Focus: This round dives into your technical skills. They’ll evaluate your knowledge of testing methodologies (manual and automated), programming languages, and your experience with testing tools. This round often includes solving real-time coding problems or answering technical questions related to quality assurance.

Common Questions:

• “What is the difference between black-box and white-box testing?”
• “Explain how you would design test cases for a new feature.”
• “Can you walk me through how you would test a web application?”
• “How would you handle a situation where you’re unable to reproduce a reported bug?”
• “What tools have you used for automated testing (e.g., Selenium, Jenkins, etc.)?”

Tip: Make sure you’re clear on various testing types (unit, integration, functional, regression, etc.), as well as automated testing frameworks. If you’ve worked with any specific tools or technologies (like Selenium, JUnit, Postman, etc.), mention them, and provide examples of how you’ve used them in your previous roles.

3. Practical Test or Technical Challenge

• Format: Take-home assignment or live coding session (typically 1-2 hours).
• Focus: This stage tests your ability to solve quality engineering problems in a practical, real-world context. You might be given a set of features or an existing application and asked to write test cases or identify bugs.

Common Tasks:

• Writing test cases for a new feature or a specific functionality in a product.
• Identifying and explaining potential flaws in an application.
• Implementing a simple automated test script.

Example Task:

• “Here is a simple form on a website where users input their email addresses. Write test cases to validate this form, including edge cases.”
• “Here is a web application that performs financial calculations. Identify any potential issues or edge cases.”

Tip: For the take-home or live coding challenge, focus on clarity and thoroughness. Write test cases that cover as many scenarios as possible (including edge cases) and ensure your automated scripts are well-structured and documented. It’s important to demonstrate your logical thinking and attention to detail.

4. Behavioral Interview

• Format: 45-minute video call with the hiring manager or team members.
• Focus: In this round, the interviewers are looking for insight into your soft skills, work ethic, and how you approach problem-solving and teamwork. Blend values collaboration, so this round focuses on how well you work with other teams (especially engineering, product, and operations).

Typical Questions:

• “Describe a time when you identified a problem during testing that others missed. How did you handle it?”
• “Tell us about a challenging bug you had to track down. How did you approach it?”
• “How do you prioritize testing tasks when there are multiple projects?”
• “How do you deal with tight deadlines or pressure when managing test cycles?”
• “Have you ever had to work with developers to reproduce a bug? How did you handle the communication?”

Tip: Be prepared to talk about real-life situations where you solved a challenging problem, communicated effectively with cross-functional teams, or dealt with a time-sensitive issue. Show that you can balance technical expertise with strong communication and teamwork skills.
