Applications support analyst interview questions shared by candidates
You have 20 balls all equal in size. They all weigh the same except for one. How do you identify the one that weighs less or more?
• Break the balls into the following groups: (1, 2, 3), (4, 5, 6), (7, 8) • Step 1. Weigh (1, 2, 3) against (4, 5, 6) Two possible outcomes: The two groups are equally heavy. (Case A) One of these groups is heavier than the other. (Case B) • Case A >> Weigh 7 against 8. Now you have identified the heavier ball in 2 weighing. • Case B >> Take the heavier group (assume it to be (1, 2, 3)), take any two balls and weigh them against each other. Either one of these is heavier else the third ball is.
The above answers is for 8 balls.
The above answer doesn't work. The unique ball can weigh less or more than the other balls. You assumed the unique ball is the heavier one.
Assessment day started with introducing yourself to other candidates. Then there were 3 tests: IT aptitude (logical thinking), math test (basic mathematics operations) and venn diagram test (all instructions were provided). The interviews consisted of technical part and another one was about your profile. Technical questions were mainly about advanced excel features, macros and SQL (RDBMS concepts). Second interview was pretty straight forward. They asked easy questions such as tell me about yourself, why are you suitable for the FDM program?
