There were two interview present and each one of them asked one problem. I was asked two question during this round. The questions were not the leetcode style and the description of the problem shared (in hacker rank codepad) were pretty verbose. The problems I will say are medium LC one's.

#1 I was share a list of table row with data in each row as #hotel_Id | # hotel_name | # city. I was asked to return the list of confusing city where a confusing city is the one in which the same hotel name appead more than 3 times. Like a mentioned, the description was pretty verbose and I have tried to make out this as the problem to solve and interview agreed. I solved it in next 20 mins & then asked a bit of optimisation and interviewer seems satisfied.

#2 The problem was similar to reversing the words in a character similar to (variation of the problem) - https://leetcode.com/problems/reverse-words-in-a-string-ii/. I was able to solve it but missed one edge case due to the way i defined the indexes in the code.

A day later, I got a reject mail from HR saying that you did good in solving both the problems (explaining time & space complexity) and have good potential but interviewer felt that you were a bit slow in solving it and also didn't follow java variable name convention and indentation properly.
