The phrase "how did you" is a common English expression used mainly to inquire about the manner, process, or experience related to a past action. It functions as a question starter, often followed by a verb, to ask about how someone accomplished or experienced something (e.g., "How did you do that?"). Additionally, "how did you" can be used in different contexts such as interview questions ("How did you hear about us?") or conversational questions ("How did you feel?"). It typically refers to something that already happened and seeks an explanation of the way or method it was done or the experience one had.
