Round 1: Written Aptitude The Vibe: Elimination round. Speed and accuracy are everything. What to practice: Quantitative math (percentages, probability, permutation), logical reasoning, and core CS fundamentals (Data Structures, OS, and DBMS snippets). Round 2: Programming Round The Vibe: Testing your foundational coding skills. What to practice: Standard Data Structures & Algorithms (DSA). Focus heavily on array manipulations, string operations, recursion, and two-pointer techniques. Aim for clean, readable code that passes all edge cases. Round 3: Advanced Programming Round The Vibe: Deep-dive problem-solving or system implementation. What to practice: Depending on the company, this will either be complex DSA (Dynamic Programming, Graphs) or a hands-on design round where you build a mini-application, custom CLI tool, or implement Object-Oriented Programming (OOP) design patterns. Round 4: HR Round The Vibe: Cultural fit, communication, and sanity check. What to practice: Be ready to walk through your resume effortlessly. Use the STAR method (Situation, Task, Action, Result) to talk about your top projects, technical challenges you've overcome, and teamwork experiences.
