Amadeus C++ Software Engineer interview questions

I took an online C++ test. The test was consisting of 20 multiple selection questions and duration was 30 minutes. All the questions were in a single basic page so there was no "Next" or "Previous" buttons etc. There was a timer but you need to click Submit yourself before 30 minutes finished. The questions were not difficult but the quality of test page (code lines, alignment etc.) and questions was not very good. I am sure at lest one question wouldn't compile at all as there was a parenthesis error. When you see a question is wrong you become suspicious of others too which is very bad.
