There were field manager and HR on the interview. First they give a AutoCAD test for 15 min, which requires knowledge of simple commands (like rotate, move, insert a block, put dimension, change text stile etc.), than questioning about your experience, attitude to work and management. Some standard questions like "What you'll do if you didn't finish you previous job and the manager is asking you to do another task?" (of course, you'll do another task, it's obvious it's more urgent); or "Tell us about your weakness" (Australian accent LOL). There's no way you can get this job without knowing AutoCAD, it doesn't have to be perfect though. Very friendly, usually they need people :)

It is a 3 part interview. The first interview is a telephone interview with their HR Manager. The second part of the interview is an AutoCAD test around 20 minutes long. And the last part is an in-person interview is with a few of their managers to go over your AutoCAD skills and see if you fit with their work environment.
