Common framework types are: Linear (record-and-playback), Modular (functions per module), Data-Driven (external data drives tests), Keyword-Driven (actions defined as keywords), Hybrid (combination), and BDD (Gherkin-based). Modern frameworks are usually Hybrid.
Linear/record-playback is quick but unmaintainable (no reuse). Modular breaks the app into reusable function modules. Data-Driven externalizes test data (Excel/CSV/JSON/DB) so one test runs many data sets. Keyword-Driven abstracts actions into keywords (Login, Click) defined in tables, letting non-coders build tests. BDD (Cucumber) expresses behavior in Gherkin. HYBRID combines the best — typically POM + data-driven + BDD + reporting — which is what most real frameworks are. Interviewers ask you to compare these and justify choosing a hybrid POM+data-driven design for maintainability and coverage.
A team's chosen design is Hybrid: POM for structure, data-driven via JSON for coverage, TestNG for orchestration, and Extent for reporting — combining strengths rather than a single pure type.
