Amazon Software Developer interview questions

Went through initial stages of recruitment process for interviews in Sydney. Spoke to HR person for 20 mins on the phone, was then directed to do a technical test. Test consisted of two simple programming problems with 1/2 hr time limit for each. Would have been easy, except you can't compile run or test your code in the web browser environment for test, unlike just about every other online coding envirnment, eg ideone.com. When I discovered this I frantically tried to get my dev env up and running on my local machine and wasted some time and only had 15 mins left for the second question, which I didn't complete. Anyway, would have been nice to know more about how the test worked in advance...
