I applied through college or university. The process took 1 day.

The OA was simple. There were two interview rounds. The interview focused on problem solving, logical puzzles, and some system design concepts like caching and database optimisation.

The HR round had one DSA, one behavioural, and one OS-based question. The interviewers were friendly, and the difficulty level was moderate.

• Find pairs with minimum absolute difference in an array (closest latency spikes). 1 answer.
• Three switches and three bulbs puzzle (enter the room only once). 1 answer.
• 100 doors puzzle (doors toggled in multiple passes). 1 answer.
• How to avoid serving stale data when using caching and data updates every 5 minutes. 1 answer.
• A database call takes 500 ms. How would you optimize it? 1 answer.

HR round: strengths and weaknesses, coordinates of two rectangles are given, how would you find if they intersect or not, and how to make your system crash using code.
