I go in with this mindset: your interviewer is not (or, at least, hopefully not) quizzing you in search of their perfect predetermined answer. They want to know how well you know yourself; how thoroughly have you researched and weighed this career? How thoughtfully have you considered what lessons life has offered you in general? Can you come to terms with the fact that you'll never know everything or be comfortable in every situation? You have (or should have) everything you need to ace this quiz already, and you got yourself through that door, so it is time to trust wholeheartedly in yourself. Yes, it helps to refresh on your application materials (wrote that puppy A MILLION YEARS before interview season) and practice trying to voice answers out loud instead of just telling yourself "oh yeah I know that one" in your head, but your genuine inner narrative should be your cornerstone. If you don't know the answer to an oddly specific or tricky question, no stress. Freely admit it and ask to learn more. Forget fretting over the uncertainty and each unexpected event during the interview. Interacting with other humans will always be nerve wracking and awkward; you only fail when you let that make you feel threatened or insecure. Just be yourself, and be respectful. And if you're worried about nerves getting the best of you, take a small pause before each answer and quickly survey- "Is this how I want to reflect myself?"
