Please define a Fourier transform and discuss how it is used?
This is a classic technical question that asks you first to define a concept and then discuss its use. When preparing for an interview, you can locate a glossary of terms used in your profession, review their definition, and then formulate a description of how they are used in the work you do. Practicing your answers to the questions out loud will make it easier for you during the actual interview.
"A Fourier transform is a method used to deconstruct basic steps to understand the overall function or process. It is typically used to understand processes involving frequencies, amplitudes, or cycles. An easy way to understand it is trying to determine the recipe used to make an entr?e in a restaurant."
