First visualize yourself shaking hands with your future boss. Light a green candle and chant the following:
Success will come unto me.
Success will come so mote it be!
Blow out the candle and visualize its energy leaving in search of new opportunities for you. On the day of your interview, visualize a purple light glowing from you that allows for all that come into contact with you to find you charming, witty, and talented.
