Alternatively you could head over to Slice and easily learn how to make them yourself for less than $2/pizza for MUCH better results with no rubbish in them: http://slice.seriouseats.com

It may not be possible, but doing a mock interview with people in a similar profession is also helpful. I did so when leaving an internship and applying for similar positions (I was leaving the state, so no hope of staying in the internship). People in the profession may ask you questions that aren't serious…
