They didn't contact me until after I passed a series of assessments. You will be contacted via a recruiter, and that recruiter may not have insight into who your future manager within the position(I asked and my recruiter stated they didn't have that information).

Initial call with the recruiter (who was very nice) and then the Hiring Manager's interview. The interview process was smooth. The whole process took about 2 weeks, tops. STAR method questions and oriented to your abilities to provide proper customer service.
