Round 1: General Aptitude Test (On-site) - 45 mins (approx).

Round 2: Problem Solving on Paper without panel. You will get a set of problems on DS & Algorithms. Write the solution on paper.

Round 3 (Continuing Round 2): Explain and optimize the code.

• String manipulation problem.
• Print Binary Tree in ZigZag manner.
• Reverse every k-nodes linkedlist.
• Given an array, find if the sum of two elements in the array gives k in O(n) time.

Round 4:

• Spring related questions - DI & IOC.
• Print Inorder without recursion.
• Producer Consumer problem, wait & sleep, synchronized keyword, and multiple related questions.
• Given a sorted rotated array, find the smallest element.
• Difference between Angular and React.
• Singleton design pattern and its variations and synchronization issues.
• Factory design patterns.
