I've included the job criteria headers to help you figure out what I was looking for in each answer; not every question fits within a specific heading. The headings were printed on the test sheet.
The Perth .NET developer market has been on fire since I arrived two years ago and SharePoint work is going through the roof; as a result, we only had a single applicant put forward for the two or three tenders that went out. When and if we have more people across this test I'll attempt to generalise the results and post an update to this post on the effectiveness of this test.
I haven't included the answer here because like I said, some of them are fairly open and a lot of them should be fairly obvious if you've done an undergraduate CS course.
