DSA Round
Discussion was on problem solving and consisted of two questions.
The first was based on the idea of Wiggle Sort, although it wasn't the standard version of the problem. The solution involved identifying and counting valleys within a wiggle-sort pattern.
The second problem was:
Find all subsequences of a given string.
I solved this using backtracking, exploring the possible choices at each position to generate the required subsequences.
Similar Pattern problem:
LLD
The problem was to design a Crypto Matching Engine.
The discussion focused on structuring the system and thinking through how the different components of a matching engine would interact.
What's Next?
According to HR, the remaining stages will be conducted from the office.
The upcoming rounds are expected to cover:
HLD / System Design
Managerial discussion
At the moment, I’m waiting for the next round.
