I dealt with a recruiter to start. They did a brief interview to see if I fit the position and explained the expectations. They pass the information on to the hiring MGR if they want to proceed. The recruiter then contacts you to set up an interview with the hiring Manager and mine was a panel (2 person). If you pass that you hear back from the recruiter after some time in which you begin giving and receiving information to get the onboarding process going. Between the recruiter interview and the hiring manager interview it was about 2-3 weeks. It can be longer or shorter depending on responsiveness of you, the recruiter and the need to fill the position.
