The best interviewing strategy is preparedness. Before The Interview Springboard into the process. Eat high-energy foods.
Interviews can sometimes run in multiples with limited breaks.
Dress for success. Make sure you are well manicured. From the tip of your toe to the top of your head. You never get a second chance to make a first impression. Also bring about the same number of business cards with your name, telephone and cell phone number, and e-mail address.
