Round 1
Round 1 happened on talscale where 3 graph based questions where asked.
Round 2:
Round 2 happened on hackerearth where a tree based question was asked. Question already available on internet.
Round 3:
This round happened in a live meeting with a juspay engineer. we were suppose to make the code written in round 2 thread safe. Making the methods synchronized was not allowed.
I was rejected after this round but I'm curious to know how exactly that could be achieved. As i could't find anything similar to that over the internet. Really appreciate if someone here knows how to do that.
