Round 1 (DSA)
https://leetcode.com/problems/serialize-and-deserialize-binary-tree/description/

Round 2 (Design)
It was around designing a logging service. Different clients should be able to integrate this service to push and monitor logs. Focus was on high scalability, optimal DB choices, Search feature for logs etc.

Round 3 (LLD)
This was more of a pair programming round. Working code was not expected but focus was more on modularity, extensibility and abstractions.
Problem was somewhat on these lines: There are boxes of different sizes (small, medium, large). Small box can fit within medium and medium can fit within large.
Implement below two features:

insertBox(Box b1, Box b2)  -> insert box b1 into b2

printBoxes() -> print all boxes currently added in the system. printing should be done in hierarchical order.
/*
	Sample print structure with boxes large(B1, B2); medium(B3, B4); small(B5, B6)

	B1
		-B3
			-B5
			-B6
		-B4
	B2
*/

Round 4 (HM)
Techno-managerial round with focus on past work experiences. OOPS, SOLID, design patterns.

Round 5 (HM)
This was an extended HM round to understand more about past experiences, future work expectations etc.

Thoughts: Process was smooth and had good interactions with the interviewers. Rounds were more focused on logical thinking rather than some fixed solution.
