Hevo Data is a rapidly growing data integration platform that empowers businesses to seamlessly move data from source systems to analytics warehouses. Founded in 2019, the company has quickly positioned itself as a leader in the SaaS data pipeline space, serving a diverse clientele ranging from startups to Fortune 500 enterprises. With a focus on simplicity, reliability, and speed, Hevo’s platform eliminates the need for complex ETL code, allowing data teams to focus on insights rather than infrastructure. As an SDE I, you will be part of the core engineering team responsible for building and maintaining the backbone of the Hevo platform. Your primary focus will be on developing SaaS connectors for a variety of applications, learning the nuances of each integration such as basic authentication, data extraction patterns, and error handling. You will also contribute to the design and implementation of lightweight REST API components, ensuring clean code, comprehensive unit tests, and efficient performance. Under mentorship, you will debug and optimize existing pipelines, improving throughput and reliability. Key Responsibilities: 1. Design, implement, and maintain SaaS connectors for new and existing applications. 2. Build and test REST API endpoints for internal services. 3. Debug performance bottlenecks in data pipelines and propose optimizations. 4. Write clear documentation for new features and bug fixes. 5. Collaborate with product and data teams to understand integration requirements. 6. Participate in code reviews and provide constructive feedback. 7. Write unit and integration tests to ensure code quality. 8. Troubleshoot and resolve production incidents related to data ingestion. 9. Contribute to the continuous improvement of engineering processes. 10. Keep abreast of industry trends in data integration and cloud services. Tech Stack: Java, Python, TypeScript, RESTful APIs, JSON, basic authentication, data pipeline orchestration tools, Git, CI/CD pipelines. Growth Path: Starting as an SDE I, you will progress to SDE II after demonstrating strong coding skills and ownership. Subsequent promotions lead to Senior SDE, Tech Lead, or Architecture roles, with opportunities to influence product direction and mentor junior engineers. Why Join Hevo? The company offers a fast-paced, collaborative environment where you can learn cutting-edge data integration technologies, work on real-world problems, and see the direct impact of your code on millions of users. You’ll benefit from a culture that values experimentation, continuous learning, and career growth, all while being part of a mission to democratize data access for businesses worldwide.

What is the difference between Implicit Wait, Explicit Wait, and Fluent Wait in Selenium? Answer β–Ό
Model Answer: Implicit Wait sets a global timeout for all element lookups. Explicit Wait pauses execution until a specific ExpectedCondition (e.g. elementToBeClickable) is met. Fluent Wait allows defining polling frequency and ignoring specific exceptions like NoSuchElementException.
Explain the Page Object Model (POM) and its advantages in Test Automation. Answer β–Ό
Model Answer: POM is a design pattern that creates an object repository for web UI elements. It separates test scripts from page locators, reducing code duplication and making maintenance easy when UI elements change.
How do you handle dynamic WebElements whose ID changes on page reload? Answer β–Ό
Model Answer: Use dynamic XPath methods like contains(), starts-with(), text(), or XPath axes (ancestor, following-sibling, parent) instead of brittle absolute paths.
What is the difference between @BeforeMethod and @BeforeClass in TestNG? Answer β–Ό
Model Answer: @BeforeClass runs once before the first test method in the current class, while @BeforeMethod executes before each individual test method.
How do you validate REST API response codes and JSON payload using Postman / RestAssured? Answer β–Ό
Model Answer: In RestAssured: given().when().get('/endpoint').then().assertThat().statusCode(200).body('status', equalTo('ACTIVE')).
