Lengthy and rigorous. SAS only leaves postings up for like a week so I was lucky to hit the window. Initial 30-minute phone conversation with hiring manager. About two weeks later, a set of in-person interviews with 2 members of the team and 2 members of HR. Then, about ten days later, more team members and the business leaders I'd be supporting. A few more days, then an offer, with no opportunity to negotiate, and contingent upon reference and background checks.
