Job fairs are wonderfully hectic and non-structured environments. Come early, and be prepared to distribute résumés and to be interviewed on the spot.

• create a one-minute "commercial" about yourself;
  
• research the participating employers before the day of the event;
  
• be curious and ask questions;
  
• hand out lots of résumés;
  
• practice your interviewing skills beforehand;
  
• dress professionally;
  
• chat with recruiters and collect business cards on which to jot down notes;
  
• ask about specific positions and salary ranges (not specific salary);
  
• follow up with companies/school systems either by mailing or e-mailing a thank you note, or by calling if appropriate.
