I received the call through a recruitment agency.

It happened on a Saturday.

The interview process consisted of:

• One round of problem-solving
• A machine coding round followed by a code review
• A design discussion

The wait times between interviews were not high, which was a good thing.

In a binary tree, if the neighbors are set on fire for every node, find the path to optimally set the entire tree on fire.

We discussed coding a system for optimally assigning orders to Delivery Executives (DEs) based on certain constraints and how it can be extended by adding more constraints. This was followed by a code review.

In a design discussion, the topic was providing an interface for Swiggy's delivery executives, displaying various statistics. The focus was on building a system design.
