Interview: Marello
Blackjack nodded. "Understandable. People who pride themselves on intelligence can often have trouble swallowing that pride when a new hire is smarter than they are. Thankfully, I have no such issue," Blackjack added with a grin, "and I'm in desperate need of someone smarter than myself. However, having a record that is grounded entirely in academics can present certain weaknesses. It's one thing to solve a problem in class or on paper, it's another thing to solve it in the real world." Blackjack opened one of the drawers of his desk and picked out a fist sized cube of metal and plastic. "I gave this same puzzle to one of the earlier applicants. They failed. I sincerely hope that you'll do better, or will at least do me the courtesy of not telling me that it's impossible." Blackjack set the cube on Dr. Marello's side of the desk. "I'll give you five minutes to put every pin into the released position. You cannot disassemble the box. The clock starts when you touch the box."
The box is a cube with four buttons on the cardinal faces, and four pins top face. The four pins are arranged as though to mark out the corners of a square roughly half the height and width of the face. Three of the pins are depressed, their heads flush with the box. One pin, the lower left, is withdrawn from the box, revealing its structure to be similar to that of a steel nail. The head of the pin is circular, and roughly twice the diameter of the solid column beneath it. On the cardinal faces of the box, in the middle of each face, is a single button. Marks on the faces of the box indicate that the top button controls the topmost two pins, the left button controls the leftmost two pins, and so forth. Pressing any button will reverse the position of the two pins it controls, so that a retracted pin will slip into the released position and a released pin will slip into the retracted position.
