Well thank the people that tried to help you, even though there is no way to be sure if it will work. All I can say is practice, you have to also remember visualization is the key. You got to know what you want the spell to do, and how it will turn out. You must mean the spell.
I am also glad you had such a great experiance in the circle. I am glad you used candles to represent the points on the pentagram. The 5 points are important, but they are not usually used a lot in finding or landing a job. I suggest trying the spell again. This time put all your emotions on how bad you want the job into it. Visualize you getting the job.
