Around 40 candidates were shortlisted for the interview. There were two rounds: a Technical Interview and an HR Interview, both conducted on the same day.

Approximately six people came from the company, and there were around 4–5 interview panels, with one interviewer in each panel.

In the technical interview, the interviewer mainly focused on projects and asked detailed questions, such as how much time it took to complete the project and other implementation-related details.

They also asked basic DSA questions, such as finding the second-highest element in an array, along with alternative approaches, their constraints, and time complexities.

One puzzle-based question was also asked. It was something like this:

There is a virus that doubles in number every second. If it takes 8 hours to fill an entire room, how much time will it take to fill half of the room?

The answer is 7 hours and 59 minutes, because the virus doubles every second, so the room must have been half-filled one second before it became completely filled.

The interviewer also discussed the mathematical representation of exponential growth, such as (2^t) and (2^{t-1}).
