Go to the bookstore or library and get a copy of "What Color is Your Parachute?"
Best career strategy book on the market. Only a couple chapters apply to interviews, specifically, but the entire book will help you understand why your interviewing for the job you THINK you want in the first place.
Oh, and if you can, schedule another interview somewhere where you don't give a rat's *ss a day or so before or just go out for dinner all dressed up the night before... sounds silly, but an hour or two beforehand trying to carry yourself will help you feel more relaxed.
. My advice would be to replace that reckoning with one that has a positive outcome. If you continually tell yourself between now and then that things are going to go smoothly and that you will feel confident and that your presentation will go well- that is what will happen. Conversely if you tell yourself over and over that it's going to be a nightmare~ it will be.
If you can visualize- use that skill between now and the time of your interview. Picture the room, the people, your powerpoint presentation- everything- right down to what you are wearing and picture it all going very well and you being comfortable the entire time. The more often you do this between now and then, the more effective it is and you'll be amazed how it will help you on that day.
May sound really hokey but it works!
Then, prepare your presentation and go in there and get the job !!
And........... breathe in, breathe out.....................
Remember, don't tell them you are a JW! No matter what.
Don’t forget about the theocratic war strategy. In reality, because of this “strategy” and other mitigating factors, Jehovah’s Witnesses are considered ineligible for many job opportunities (from knowledgeable employers) which require a history of trust, emotional stability, rational & analytical thinking.
