First contact with HR person, with a quick interview of about 30 minutes, asked about my experience in general and talked a little about the company. Then the technical interview conversation was scheduled with a machine learning engineer from the company, this conversation was about general aspects of ML, talk a little and then ask a specific question. All very polite and helpful.

Phone screen with HR, then phone interview and on-site interviews. The whole thing was well-organized and pretty quick. Interviews had a fairly standard format, with 1 fit interview, 2 CS interviews and 1 deep learning interview
