Pretty fluid interview. Talked through my entire resume with my would be superior and a software guy who occasionally chimed in. Had me talk through projects, experience. Had a tour of the office space afterwards, then got to ask questions. Probably Longer than it needed to be at about 2 hours. They had another software guy call me 10 days later and give me a cursory phone interview about software topics totally irrelevant to the job I applied to. Got ghosted after all that.
