It was an amazing experience.

I arrived at 12:45 pm, and the first round started at 1:00 pm sharp. The interviewer was a Software Engineer. He asked me about my projects, one data structures question, some Operating Systems related questions, and some general "What do you want in life?" type of questions. This round lasted for one hour.

He left when the next interviewer arrived. This interviewer was also a Software Engineer. He also began with a project discussion. Then, we discussed a class design question. He then asked me some follow-up questions based on the solution I presented. This round also lasted for an hour.

After that, there was another technical round with a Software Engineer. He also asked me about my resume and a project in detail, and then proceeded to ask an algorithm/data structures question, followed by some follow-up questions on that. This round also lasted for one hour.

At exactly 4:00 pm (the scheduled end time), my last interviewer walked me out of the building and informed me that the recruitment coordinator would be in touch in a few days.

I received the response the next working day.

Overall, it was a smooth and time-efficient process, and they treated me very well.
