Two phone screening calls, audio only. Asked me different questions about my background and accomplishments, but no questions about technical interviews. Got an offer for a final onsite interview which was about 5 interviews and about 5 hours long. Overall, this was a good experience, and 3/5 interviews were more interpersonal than technical. Two interviews centered around computer vision, architecture, and hardware questions. I would rate this as a negative experience overall, however, because the reason I did not get the hire was a lack of technical skills, which they only asked me questions about after 2 weeks during the onsite interview, and not right away. This meant that ultimately I had gotten my hopes up and gone through a 5 hour interview process that was largely obsolete. If they would just ask the technical questions that could disqualify you right away, they would save themselves and others a lot of time.
