I got asked the button question. Essentially they drew out a layout where there was a top surface, a bottom surface, a spring, a button, and a switch. The goal of the question was to find out what part of the drawing had to switch locations based on the drawing given. The question was a lot easier than it seemed. The switch, which the button was supposed to press as the spring compresses, was off centered, As a result, the fix to the question is to move the switch so that is aligned vertically with the button.
