3-4 rounds Coding questions: * Merge sort * Detect & remove loop from linked list * Reversal of linked list * Count number of 1s in binary of a number * Shortest path in graph * Check if tree is BST or not Design patterns: * Singleton * Factory

It was easy and had only one round. They asked questions based on data structures, SQL, and OS. They took an introduction and asked a few theoretical questions. The interview lasted for 1 hour.

It was a simple, two-stage process: first, a telephonic screening, followed by a face-to-face interview. The second round had a panel of four people with easy to moderate interview questions.
