  • Matrix rotation inplace (space optimized)
  • Right view BST
  • Top view BST
  • Clone linked list with random pointer
  • Check if number is power of 2. No inbuilt function can be used.

Only approach were required. In the end he asked me few theoretical questions from Operating System like,  What is process? PCB? Stack Heap Registers

From the combined result of 3rd and 4th round approx 8 were sent to the 5th round which was managerial round.

Round 5: F2F Interview Managerial Round.

The interviewer was very experienced person, though he was very friendly in nature. He made me comfortable as he saw I was a bit nervous. He asked me about my internship projects as I mentioned it on my Resume, and dived deep into the technical details. As I was well prepared and knew the things, I could explain him in a better way, which I believe, gave me a huge benefit. He seemed impressed from my in-depth knowledge. Then he asked me 2 puzzles, luckily I could solve the both. Then he signalled me to move to HR round.

Approximately 5 could make it to HR.

Round 6: HR Round

Worlds most famous HR questions like:

  • Where do you see your self 5 years down the line?
  • Why Informatica?
  • Strengths and Weaknesses.
  • Rate your self out of 10 for problem solving ability.
  • 2 puzzles.
