First is a phone screen with a recruiter to cover basics about your experience, then a technical interview with an engineer going over past projects and mechanical engineering fundamentals questions. Final round is onsite with presentation of a past project and 3 45 minute interviews with engineers in different departments.

Phone call with HR recruiter to talk about company culture and objectives and brief overview of experience. Very simple and straight forward. Next step was with hiring manager for the team - more in depth discussion of experience and handful of first principles questions (GD&T, material properties, etc). Hiring managers seem to be on the younger end (early 30s). If rejected, don't expect any further communication to get feedback as it doesn't happen. Recruiters don't try to follow up, which is annoying, but makes sense since they are hiring people so fast and can't keep talking to multiple candidates.
