Product design engineer interview questions shared by candidates
What are the different ways you can you tell if this part is steel or aluminium.
Simply by using a magnet, Steel has metallic properties, and the magnet will connect. Aluminium will do nothing.
Many stainless steel alloys are not magnetic, so if your magnet is attracted to the material you will definitely know it is steel, but if it doesn't you will not know what the material is.
Simple methods would be density (feeling the mass of the object), surface finish (color, texture). If coated that may give you the answer i.ie anodized would indicate aluminium. For more information I would go for EDX( Energy-dispersive X-ray spectroscopy) and possible a cross section to look at the grain structure.
Questions that popped out as I can remember. 1) A cube (1-1-1m) of ice in a room (50C) sitting on a wooden table. the ice is 1m away from the walls around it's 4 sides, except for 1 side is 30cm away. You're given 2 insulating blankets (1m by 1m) that can be used to cover the ice block. The goal is to keep the ice in solid form as long as possible. Where would you put the blankets? 2) 2 rectangular beams, one is Aluminum a by 2b cross-section one is Steel a by b cross-section. If you were to climb a mountain and find these two sticking out on a spot where you need to rest, which one would you latch on to? 3) Interviewee shows a plastic part and asks: How do you think I built this part? What other ways can you think of this part could have been done?
Suppose a theater company calls and requests that a drum be custom fitted to appear inside a large barrel and sounding a certain way. Describe the design process you would use to accomplish this.
