Round 1: Online Technical Interview This round is primarily focused on assessing the candidate’s problem-solving skills, algorithmic thinking, and technical expertise. It typically includes: Data Structures & Algorithms (DSA): Candidates are expected to solve coding problems that evaluate their understanding of core concepts such as arrays, strings, linked lists, trees, graphs, sorting, searching, recursion, dynamic programming, etc. Technical Knowledge: This section involves in-depth questions related to: JavaScript: Concepts such as closures, asynchronous programming (callbacks, promises, async/await), event loop, scopes, hoisting, ES6+ features, and design patterns. Node.js: Understanding of event-driven architecture, middleware, Express.js framework, RESTful APIs, asynchronous operations, and commonly used Node.js modules. Databases: Both SQL (e.g., MySQL, PostgreSQL) and NoSQL (e.g., MongoDB) concepts including schema design, normalization, indexing, joins, transactions, and query optimization. Round 2: Human Resources (HR) Interview The second round focuses on evaluating the candidate’s personality, communication skills, and cultural fit within the organization.
