Interview
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?
The Interview Process was not that much difficult as people think It was like normal interviews just with some moderate DSA problems, OOP and DBMS problems were also asked in my interview so better to prepare these three before going to the interview
