C-DAC Interview Question:

This is a process guesstimate where the interviewer wants to know if you know what to ask. First, you would find out the dimensions of the building (height, weight, depth). This will allow you to determine the volume of the building. Does it taper at the top? (Yes.) Then, you need to estimate the composition of the Chrysler building. Is it mostly steel? Concrete? How much would those components weigh per square inch? Remember the extra step: find out whether you're considering the building totally empty or with office furniture, people, etc. If you're including the contents, you might have to add 20 percent or so to the building's weight.
