If you are an introvert and new to the yearbook staff, here are pieces of advice I can give you regarding interviewing students at your school:
1.) Do not be afraid to knock on the door and ask the teacher if you can interview a certain student. Sometimes, a teacher will get angry at you for interrupting their class, but do not take it personally and maintain a confident, polite posture.
2.) When you interview the student, ask one to three questions about the topic you are covering for a certain page in the yearbook. Look directly at them in the eyes and jot down your questions and their answers.
3.) Before you send them back to the classroom, ask if you can clarify their answers because it is essential as the interviewer to make sure you do not misinterpret what they have said.
