I've had a few different types of interviews with SAP which generally fall into one of the process categories below: 1) standard, 2-4 rounds 2) simple, screening with recruiter, then just hiring manager 3) 3 rounds of panel interviews (2-3 people each), 45 mins each round 4) screening, then presentation of project portfolio with 4 person team 5) screening, then demo of work or solving a problem
