Round 1 was aptitude round, it consisted of java and c++ snippets and we had to guess the output. Apart from that there were problems on speed, velocity, distance and time. Problems on word-letter patterns were also asked. The aptitude round had 30 questions and time given was 30 minutes.

Aptitude round was the only elimination round. The next following 4 rounds were non-elimination rounds. Coding test included 3 questions - 1 and half hour was given to solve the same. It is fine if you don't perform well here, since it is a non-elimination round. But try to solve 1 and half or 2 questions atleast. The questions were mainly based on 1d arrays, 2D arrays, strings and string arrays.

Shortcut Tips for Coding Tests: 1. Master the Basics: Familiarize yourself with arrays, strings, loops, and conditional statements. 2. Learn Patterns: Concentrate on sliding window, two-pointer techniques, recursion, and divide-and-conquer methods. 3. Use Standard Algorithms: Study breadth-first search (BFS), depth-first search (DFS), sorting algorithms, and dynamic programming principles. 4. Understand Data Structures: Practice with stacks, queues, linked lists, and trees. 5. Practice Edge Cases: Consider scenarios involving empty inputs, duplicates, and large datasets. 6. Write Pseudocode: Outline your plan before starting to code. 7. Optimize Early: Always strive for efficiency in your solutions.
