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.

Q6. Access Modifiers in java
Ans. 
Access modifiers in Java control the visibility of classes, methods, and variables.
• There are four types of access modifiers in Java: public, private, protected, and default.

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.

Q3. What is recursion, write a code for it
Ans. 
Recursion is a programming technique where a function calls itself to solve a problem.
• Recursion involves breaking down a problem into smaller subproblems and solving them recursively.

• A base case is needed to stop the recursion and prevent infinite loops.

• Example: Factorial calculation using recursion - function factorial(n) { return n === 0 ? 1 : n * factorial(n-1); }
