Round 1: Coderpad DSA

• Q1 - Given a list of parent->child associations, find out the root node of the largest tree
• Q2 - A refarming of Maximum Path Sum - DP

I passed all the tests for both.

SuperDay Rounds - Pass each one to progress to next

Round 1:

Q1 - Pseudo code for logic of heap add function
Q2 - Pseudo code for Valid BST
Q3 - Given a list of roles, and each role migh have parent, acceptlist, denylist, e.g. read/write permissions. Write the logic for getPermission function when supplied with a role. Certain rules - Child carries all permissions of parent. Child permissions override parents' , Follow Up - What if there are multiple parents.

Got a call after 20 minutes to proceed with the next round.

Round 2:

Q1 - System design for a live chat system on a streaming platform - e.g. Youtube Live

Q2 - LLD for an in memory job scheduler (support concurrency). Later on asked to design the same for a distributed system.

Verdict:-

Reject. No feedback given. No call back. Just an auto rejection mail within a few minutes of the last round.

The HR was not flexible at all. No time, or day flexibility was given. Even the times were confirmed the evening before the rounds. I had 1 day between coderpad round and the first call, and 1 day again between Superday rounds and coderpad.

The rounds were named something else, but proceeded to expect something else.

Overall - Be ready to face anything thrown at your way, and hope you get lucky. Recruiters are talking with a sense of entitlement these days. Everyone wants you to be ready to give 4 rounds of interview the next day like you are just sitting and waiting for them and don't have any other committments.
