The interview is there for us to get to know each other better and get to know yourself better.
Who are you?
Try answering this question again and again. Who are you really? Who are you behind the first easy answers? Who are you when you look deeper?
The interview questions are designed to help you look at yourself and the world at different angles, to reveal more about yourself than just your name, job, gender and such, and maybe even prompt a more in-depth conversation with others.
All members can fill out the interview at their discretion and add it to their profiles. If you choose not to, that's ok too. You can always edit and change your interview later on.
