My interview experience at Folio3 was straightforward. The focus was on core concepts: OOP principles, database topics (joins, normalization), and fundamental data structures (linked lists, trees, arrays, stacks). IQ problem-solving was also tested with puzzles involving coin weight and water jug capacities. Overall, the interview covered essential technical and problem-solving skills.
Heavier Coin Puzzle: You are given a set of nine identical-looking coins, out of which one coin is heavier than the others. You have a balance scale that you can use only twice. How would you identify the heavier coin?
Water Jug Problem: You have two water jugs, one that can hold 8 liters and another that can hold 5 liters. You also have access to an unlimited supply of water. Your goal is to measure out exactly 4 liters of water using these jugs.
Water Jug Problem: You have three water jugs with capacities of 8 liters, 5 liters, and 3 liters. Currently, the 8-liter jug is filled with water. Your task is to measure exactly 4 liters of water. You can use the jugs to transfer water between them, but you cannot estimate quantities. How can you achieve the goal?
