UserTesting India SDET Interview: Rounds, Questions and Preparation

What the job involves

As an SDET at a global tech company like UserTesting India, you will design, build, and maintain automated test frameworks and test suites for web and mobile applications. You will work closely with developers and product managers to ensure high-quality releases, often owning the test automation strategy for a feature or product area. Day to day involves writing code in languages like Java or Python, using tools like Selenium, Appium, and REST Assured, and integrating tests into CI/CD pipelines.

Role and Technical Knowledge

1. 1

   What is the difference between a QA engineer and an SDET, and why do companies like UserTesting India hire SDETs?

   Highlight that SDETs write production-level automation code, build frameworks, and contribute to test strategy, while QA engineers may focus more on manual testing. Mention that SDETs enable faster, reliable releases in agile environments.

2. 2

   Explain the Page Object Model (POM) in Selenium. How does it help in maintaining test code?

   Describe POM as a design pattern where each web page is represented as a class, with locators and methods. Emphasize reusability, reduced duplication, and easier maintenance when UI changes.

3. 3

   How do you test a REST API? What are the key things you validate in an API response?

   Cover status codes, response body (JSON/XML), headers, response time, and authentication. Mention tools like REST Assured or Postman and how to automate these checks.

4. 4

   What is the difference between a stub and a mock in testing? When would you use each?

   Explain that stubs provide canned answers, while mocks verify interactions. Use stubs for state verification and mocks for behavior verification, especially in unit or integration tests.

Practical Scenarios and Automation

1. 5

   You have a web application with dynamic elements that change IDs on every page load. How would you locate these elements in Selenium?

   Suggest using relative XPath, CSS selectors with stable attributes, or waiting strategies. Mention avoiding absolute XPaths and using explicit waits for dynamic elements.

2. 6

   How would you integrate your Selenium test suite into a CI/CD pipeline like Jenkins?

   Describe creating a Jenkins job, configuring it to pull code from Git, running tests via Maven or Gradle, and publishing reports. Mention triggering tests on every commit or nightly builds.

3. 7

   You need to test a scenario where a user uploads a file and then downloads a report. How would you automate this end-to-end?

   Cover using Selenium's sendKeys for file upload, and for download, configure browser preferences to save files to a known location, then verify the file exists and its contents.

4. 8

   How do you handle test data management in your automation framework?

   Discuss using external files like Excel, CSV, or JSON, or databases. Mention data-driven testing with TestNG DataProvider and keeping test data separate from code.

Behavioural and Situational

1. 9

   Tell me about a time you found a critical bug late in the development cycle. How did you handle it?

   Use STAR method: describe the situation, your action (e.g., communicating with team, prioritizing fix), and the result (e.g., bug fixed, process improved). Show ownership and communication.

2. 10

   Describe a situation where you had to learn a new automation tool or technology quickly. How did you approach it?

   Highlight self-learning, online resources, practice projects, and applying it to work. Emphasize adaptability and eagerness to learn.

3. 11

   How do you prioritize testing when you have limited time before a release?

   Explain risk-based testing: focus on critical functionalities, high-risk areas, and regression suites. Mention collaboration with product and dev teams to align priorities.

4. 12

   Give an example of a time you disagreed with a developer about a bug. How did you resolve it?

   Show diplomacy: provide evidence (logs, screenshots), discuss impact, and involve the team if needed. Focus on resolution and maintaining good relationships.

HR and Company Fit

1. 13

   Why do you want to work as an SDET at a company like UserTesting India?

   Research the company's product (user testing platform) and connect it to your interest in quality and automation. Mention the scale and impact of testing on user experience.

2. 14

   Where do you see yourself in the next 3 to 5 years in test automation?

   Show ambition to grow into a senior SDET or test architect role, deepen expertise in AI-driven testing or DevOps, and contribute to open source or internal tools.

3. 15

   How do you keep your automation skills up to date with evolving technologies?

   Mention following blogs, taking online courses, contributing to GitHub, and experimenting with new tools like Cypress or Playwright. Show continuous learning.

4. 16

   What are your salary expectations for this role?

   Research industry standards for fresher SDETs in India. Provide a range based on company size and location, and express flexibility and focus on learning.
