I applied online. The process took 4 weeks. I interviewed at National Instruments in January 2016.
Assessment day consisting of technical and personal interviews, a technical presentation, and group tasks - They often take you out for a meal in the evening too!
They give you lots of opportunity to ask whatever questions you have - a tour around the facilities to meet current grads on the program and see their table tennis table.
Personal - Typical interview questions about your past experiences,university and skills, targeted towards their competencies.
