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.
