When you Interview for job, audition, or club, there is a etiquette.

Be on time! In fact, be sure to get there early. If you get there just in time, you will still be nervous from the finding the right building and the right office. So, get there early, find the building and the office, and then copose u !When Koreans people meet someone[have an appointment], they are late 20~30 minutes. It call ‘Korean time’. It will give uncomfortable to  examiner. May be you can’t pass thel interview becasue of your habit. When my club interview university students, people who were late was failed the club.
