Problem solving questions include: If it is 3:15 what is the number of degrees between the hour and minute hand (7.5). They also ask typical marble problem solving questions such as if you have 9 marbles and a scale with two weight scales on either side what is the minimum number of times you would have to weigh the marbles to find the heaviest one. Also, they might ask the "3 and 5 L bucket" question. Other than that, pretty typical. How do you cope in stressful situations? Are you ok working in a harsh environment. I felt like that sort of try to scare you off a bit, likely because the second interview involves flights and hotels and they want to make sure you are serious.
