You can do a petition spell if you are too new. For manipulating interviewers and getting a job KIng paimon, Bune and Belial will be very helpful.
before reading petition spell aloud and burning it, Chants enn’s of entity who you writing letter of intent, While being in a relaxed state. And also EA conjuration of limitless power 9 times as suggested in the above tutorial, I believe the conjuration is in the first reply.
As you are a newbie to magick, I will also suggest you to do a banishing in the area after completing letter of intent.
