How to Use These Guides Effectively
- Find your target company in the tables above and open its guide.
- Read the hiring process section first — understand what each round tests before jumping into questions.
- Solve the OA questions under timed conditions — simulate the real exam with a 60–90 minute window.
- For each problem, attempt it yourself first, then check the approach hint. Never read the solution without trying.
- Practice on platforms like LeetCode, HackerRank, or GeeksforGeeks to get used to the submission environment.
- Track your weak topics — if you struggle on graph problems across multiple companies, dedicate focused time to BFS/DFS before revisiting.
