Just thought of another tip. If asked your greatest weakness, say it is your lack of experience. Works a charm for interviewees right out of college.
If I were to memorize 5-10 key facts/figures about the economy what should they be? Obviously I might not actually mention them in the interview if it doesn’t come up but I believe that I might impress the interviewer if I do incorporate some figures into my answers when applicable just to give the illusion that I my brain is a plethora of knowledge lol
