One phone interview followed by one in-office interview. The phone interview was basically a more-detailed resume review with the hiring manager. Occasionally an additional pre-screening call may be used, as well, sometimes with 2-3 "basic" technical questions. The in-person interview tends to be a three-part visit to the department director, then the lead architect, and then the hiring manager, each with 1 or 2 subordinates for additional questioning. The questions start high-level but become more technical at each stop. The hiring manager usually has a lead and senior developer in the interview who ask several technical questions, including a couple "trick" or extremely advanced questions with the intent of evaluating the quality of an "I don't know" response.
