You've probably heard this advice too many times, but it MUST be repeated here: First impressions are critical, especially so at a career fair where you have such a short time with each recruiter. If you blow that first impression, you've lost that opportunity.

How do you make a good first impression?

The four key ingredients to a good first impression are:

• Short introduction using a natural, but forceful voice (especially if you are typically a quiet person; but please, no shouting)
• Strong eye contact
• Firm handshake (not limp, damp, or bone-crushing)
• Gentle smile

And if there is a long line to meet the recruiter, remember to relax and not get over-anxious -- or worse, to make noises like your time is more important than anyone else's.
