Spoke with HR and Hiring Manager separately, then a "final round" of a day's worth of interviews. Asked to create a presentation and present. Was very impressed with the process - it was collaborative and designed to help me put my best foot forward.

Multiple 1-o-1 casual conversation with Manager, HR and other team members for screening, Formal presentation followed by multiple 1-o-1 interviews with all team members which roughly takes an entire day, references and the management schedules call with them and finally offers are released.
