I just went through the first round of phone interviews and it was fairly straightforward. I talked with someone about my academic, former internships, and future careers goals. I received notification the very next day that I had advanced to second rounds on site interviews and we scheduled for a two day interview, for me to arrive the day before my all day final round in Madison and to have dinner with an employee. Overall, I think the experience was very positive. There was great communication and quick turnaround from the human resources/ recruiting contact and also from my interviewer.
