Autodesk has many diverse business units with various job levels. I doubt there is any set interview style. You will likely be interviewed by several members of the team you would be hired into along with key members of closely associated teams. Each member of the interview team will have their own focus. Some may be looking for specific areas of technical competency while others may be interested in social skills and how you react to certain situations.
As with any job interview: get a good nights sleep the night before, dress appropriately, try to know something about the software/market of the group you hope to join and smile.
