I applied online. The process took 2 weeks.

After clearing the Online Assessment, I was invited to the team screen interview round. It was a coding exercise round and the question was quite similar to what you have already attempted in the OA. It was not a regular LeetCode-style question, but a long implementation-based problem. These types of problems generally don't require heavy data structures, but only clean and scalable code from the very beginning, like using structs to club same entities, etc.

How can you write a cleaner version of this code, which is scalable enough that if we need to change some parameters we don't need to change the whole code?
