Topics Asked: Algorithms, Array manipulation (2D array traversal)

Experience:

During a technical phone screen for a Software Engineer position, a candidate was presented with a specific coding challenge. The problem involved an N x N array that needed to be filled with consecutive integers. The filling process started with '1' in the center cell, then proceeded in a spiral pattern: '2' down, '3' left, '4' up, '5' up, '6' right, '7' right, and so on, continuing to fill the array until all cells contained a number. An example of a 7x7 array was used to illustrate the expected spiral traversal and filling logic.
