You'll have to do a pitch for a product not necessarily to do with the industry but that you know well. This is done either via Skype before an interview or in person. The interview itself felt like a bit of a grilling so make sure you can demonstrate that you know your figures but the people there are friendly, decent and professional. They are a manufacturer first and foremost rather than machinery dealers so make sure you ask as many questions as possible (targets, ownership of area, etc) yourself to make sure you understand the role is right for you.
