At a job fair, you can talk to editors from larger papers and learn about their requirements and expectations. This will give you an opportunity to think about long-term goals. Ask recruiters what you need to do to become competitive for a job. Discuss the comparative rewards of different newspaper career paths. Personal appearance is important.
Business attire is always appropriate.
Conduct yourself properly. Make direct eye contact with the interviewer. Maintain good posture. Give honest, concise answers. Remember names of those you meet and use them in conversation.
