Palpitate

I'm staying in Australia for three month. I'm looking for a job. And I have an interview tomorrow, so I am nervous. I hope the work is determined the interview is successful. OR I hope I get the job. OR I hope they hire me. OR I hope they choose me. OR I hope they will decide who gets the job quickly.

I'm staying in Australia for three months and am looking for a job. I'm nervous because I have an interview tomorrow. I hope the work is challenging.

Notes:
This is how I would say it. The word determined doesn't make sense in the way you used it. Challenging works, or any of Michael's suggestions work too! :) Overall, great job!
