Three rounds below: Recruiter round - talk with a recruiter to determine high-level fit, based on further information about the company and the posting, plus some elaboration on your own background. Hiring manager + other stakeholders - a bit longer and more detailed talk with a group closer to the work, including the hiring manager, again gauging fit at a somewhat high-level. Case - prepare a solution, over the course of a few days, satisfying certain requirements related to the actual job responsibilities.

Interview process was a great experience and the process, next steps were well updated by HR and the hiring manager. The case study round is something very interesting, which also gives the candidates a understanding of what the role expects from you.
