There is an initial screening interview with HR, then a first round interview with senior modeler, followed by a second round with the Director, and a final round with the VP with presentations

Phone screen with the HR rep, phone interview with an employee, in person interview+office tour with 2 equity holders, final Skype interview with SVP and CEO. Mostly normal interview questions: strengths/weaknesses, time you made a mistake, ideal work day, etc. Other logic questions which weren't too hard and a few questions about the Mississippi River from the CEO, which I thought was odd.
