Long. I was there for more than four hours (not because it was fun or going well) and it was a round of meetings with the operations person, CEO, and the head analyst. There were questions about why I cared about technology and what I knew about the field. Basically just ask the CEO about his Ferrari, he loves to talk about himself. And don't tell them you like Apple products.
They make a lot of promises about how you will be a thought leader in the industry and help shape technology. But there is no research education, method or standards, that's why they don't ask any questions different research methods and writing techniques.
