Interview Round: Technical Screen
Overview: This multi-part prompt evaluates core software engineering competencies including Python fundamentals (OOP, object/model behavior, iterators/generators, decorators, serialization), data structures and algorithms (lists, trees, sorting and complexity), databases and web/OS concepts (indexes, B+ trees, ACID, joins, process vs thread, page-load flow), and testing/QA risk analysis for modules like data connections, user management and payment flows. It is commonly asked within the Software Engineering Fundamentals domain to measure both conceptual understanding and practical application, emphasizing trade-off reasoning, system-level thinking and testability awareness rather than implementation details.
