Starts with a phone screen, your usual recruiter questions. Nothing technical other than talking about any past experiences you may have had. If they like you, they'll send you a CCAT assessment and a Codility exam (2 hours, 3 problems).
If you do well enough there, then you get the onsite. 3.5+ hours of interviewing. 3 technical interviews, one behavioral. Java DS/A stuff. Whiteboards. Met with potential team members, a manager, and tech leads.
