Round lasts for 60 mins and it contains 3 System design scenarios and we need to answer how do we handle those scenarios - 10 mins . Scenarios will be pretty much like how do you save cost for the company and how do you scale resources . Next session I had 6 questions on Object oriented design and production issues. Next session has 2 leetcode problems one is on hashmap and the other is on finding the word in matrix .
