When the Google interviewer asks you to describe something, you should immediately identify the question as being technical. When responding to a technical question, you first define the term or concept and then describe how it is used in the work you are performing. If the interviewer asks you follow-up questions, they are expressing a strong interest in this topic and indicating that it is important to their operations. This is a signal for you to expand on your answer and give them more details than you normally would.

"A stack is a data structure that has several distinct characteristics. Stacks use a LIFO process, organizing the data as last in, first out. This differs from a queue, which processes data as first-in, first-out. The two operations a stack performs are push, which is insertion of the data at the top of the stack, and pop, which is removal of the last item added to the stack."
