programmer analyst interview questions shared by candidates
Given 9 ball with only one differ in weight, how to find out by measuring them only twice?
Take 3 balls each. Weigh by keeping 3 on one side and three on other and keep the remaining 3 aside. 1. If the weigh comes as equal u know the ball with diff in weight is in the three kept aside. So again weigh by keeping one of the three on one side and one on other . If equal the third one is the one that differs in weight else ur weighing machine will tell u the one which differs in weight. 2. If initial weighing is not equal follow step one for the weigh which shows the diff
Drop them from a sufficient height. If 8 balls land first your 9th is the lightest, if 1 lands first, it's heavier than rest. 1 go, do I get brownie points?
The above is so stupid...even Galileo knew that couldn't happen...and that was over 300 years ago...
In the final interview, I was asked about solving a specific problem within the context of my presentation. "Given the market for (chosen company) contains only one other competitor that is as large, how do you think KPMG can bring real value to them with our consulting advice?"
