Start by learning testing fundamentals — SDLC, STLC, test case design techniques, and bug reporting — along with basic SQL and a bit of Java or Python. Enrolling in a structured software testing course (free or paid) helps, but hands-on practice matters more than certificates. Learn one automation tool like Selenium or Playwright, build a small project portfolio, and apply for QA internships and fresher roles on Naukri and LinkedIn. ISTQB Foundation can add credibility for service-company roles.

Software testing is the process of checking whether an application works as expected and finding defects before users do. It is important because it prevents bugs from reaching production, protects the company's reputation, reduces the cost of fixing issues later, and ensures the product is secure, reliable, and delivers a good user experience.

The software testing life cycle (STLC) is a step-by-step process teams follow to test software in a structured way. It has six phases: requirement analysis, test planning, test case development, environment setup, test execution, and test cycle closure. Each phase has defined entry and exit criteria, which makes testing organised, repeatable, and easier to track.

Practice on real, publicly available applications instead of only reading theory. Explore apps like e-commerce sites or banking demos, write test cases and bug reports for them, and try breaking them deliberately. Move on to automating a few flows with Selenium or Playwright, practise API testing with Postman, and join testing communities or open-source projects where you can share your test ideas and get feedback.

Start with Jira for bug tracking and test management, Postman for API testing, and Selenium or Playwright for web automation — these appear in most Indian job descriptions. Add Appium if you are interested in mobile testing, JMeter for performance basics, and Jenkins or GitHub Actions to understand CI/CD. Mastering one automation tool deeply is better than knowing five superficially.

Expect questions on verification vs validation, severity vs priority, smoke vs sanity testing, regression testing vs retesting, the bug life cycle, and test case design techniques like boundary value analysis and equivalence partitioning. Interviewers also often ask you to write test scenarios for a random object like a pen, lift, or login page, so practise thinking out loud and structuring your answers.

Build a small portfolio — a few practice test plans, well-written bug reports, and one automation project on GitHub — then apply to service companies and startups, which hire freshers in volume. Optimise your Naukri and LinkedIn profiles with keywords like "manual testing" and "Selenium", ask for referrals, take internships to get initial experience, and consider ISTQB Foundation for an extra edge.

Test automation means using scripts and tools to execute tests automatically instead of manually clicking through the application. It is mainly used for repetitive checks like regression suites, saving time and catching bugs early in CI/CD pipelines. Not everything should be automated — exploratory, usability, and frequently changing features are usually still tested manually.

A test automation framework is the structured set of guidelines, libraries, and reusable components used to build and maintain automated tests — things like folder structure, page object classes, utilities, reporting, and test data handling. Common approaches include data-driven, keyword-driven, modular, and hybrid frameworks. A good framework lets multiple engineers write consistent, low-maintenance tests instead of copy-pasting scripts.

It varies with skills, city, and company type. Freshers typically start around ₹3.5–6 LPA, engineers with 3–5 years of solid automation experience usually earn ₹8–18 LPA, and senior automation engineers or framework architects at product companies and MNCs can make ₹20–40+ LPA. Strong coding skills and framework design experience are what move you into the higher brackets.

An SDET (Software Development Engineer in Test) is a developer who specialises in testing. Unlike a manual tester, an SDET writes code to build automation frameworks, testing tools, and CI pipelines, and contributes to unit, API, and performance testing. In product companies, SDETs sit within the engineering team and are involved from design through release.

Yes, especially if you enjoy coding. Product companies, unicorns, and MNCs in India hire SDETs at salaries close to developer roles, and demand is growing as teams ship faster and need engineers who can build test frameworks and infrastructure. The trade-off is that the bar is higher — you need strong programming, DSA, and design skills, not just tool knowledge. Growth paths include SDET lead, QA architect, and engineering productivity roles.

Prepare in four tracks: coding (arrays, strings, hashmaps, and basic DSA in Java or Python), automation (Selenium or Playwright, framework design, waits, page object model), API and database testing (Rest Assured or Postman, SQL joins), and scenario questions like "how would you test WhatsApp?". Review the company's tech stack, practise explaining your past projects end-to-end, and do a few mock interviews to sharpen your communication under pressure.

Typical rounds cover the difference between an SDET and a manual tester, test scenarios for everyday apps like a lift, payment flow, or login page, how you would design a framework from scratch, the bug life cycle, and CI/CD basics. The sdet interview coding questions usually involve string and array problems, finding duplicates, writing a small utility or API test in code, and occasionally SQL queries. For senior roles, expect system design questions around building a scalable test framework.

For web UI practice, use demo e-commerce and sandbox applications such as Automation Exercise, Sauce Demo, and The Internet, which include login, cart, and form flows. For APIs, practise on ReqRes, JSONPlaceholder, and RESTful Booker. Pick one site and build a small framework around it rather than automating everything — a well-structured mini project is exactly what interviewers want to see.
