My first experience with Swiggy was bad, and I had given negative feedback on Glassdoor. Later, the HR approached me and invited me for another round of interviews.

I appreciate their gesture in addressing the concern. The effort to trace back an anonymous review is commendable.

The first round was around 2.5 hours with the CTO. He presented a real-life problem that Swiggy faced, and we worked on a solution. This was followed by a design discussion, during which there was healthy debate.

The second round was for an hour with the Director of Engineering. We discussed my passion, my work experience, and why I was interested in Swiggy. The discussion was again healthy.

The third round was machine coding. It was a relatively simpler problem compared to the first round, but the approach, extensibility, and test cases mattered.

Implement a Cache that works on Least Recently Used (LRU) and Last-In, First-Out (LIFO) principles.

The design should be extendible to support more logic, such as the most frequently used element.
