Commercial Professional Job Fairs These general professional job fairs are geared to a wide range of professional occupations, from accounting to programming to engineering to sales. Be aware that you are running with a new herd at this one. You have to be prepared to compete directly with those who have practical work experience in the field. Get ready to hear a lot of nos, but the occasional employer that does have a need at the entry level could make it worthwhile. Your main objective should be to gather information for later direct follow-up with the employers. Do not expect anyone to call you back based only on dropping off a resume.
