The process was very long. I applied online and after a few days I received a phone call from a recruiter. She proposed a time for an interview in three weeks. I had a phone interview with a hiring manager and it was rather good. Quite pleasant conversation and the managed also wanted to describe his team tasks, that was actually very interesting position and I honestly said that to the manager. He also gave me positive feedback after the interview and promised to come back very soon with further steps. However, no one ever called back. After a month I called to SAP careers help line, hoping to reach HR about the status. It looks like SAP uses trainees to pick that phone, as person replied was not really helpful and only confirmed the application is "in process" and someone will call me back soon. Only after two months I got standard and system generated reply that I was not selected, with no reasons explained. Recruiter however did reply to my email and told that position was closed because of budget cut. Which I doubt to be the real reason as position was opened for almost half a year.

3 rounds of interviews: quick prescreening call with HR, on-site meeting with the manager, and a tech call with the lead engineer. Prescreening was as usual. On the same day, I got a call from the manager and planned a second round for the next workday. The second round was the most important. First quick introduction, then easy puzzle, then 15 min of technical questions (OOP, basic programming principles, Relational DBs, etc) - pretty easy, nothing too deep. Then, about 40 minutes talk about previous experience, position, hobbies, and other basic topics. Very pleasant and friendly, good atmosphere. The third round was very quick - no live coding, a couple of architectural questions, static code analysis, and how to improve it (N+1 problem), SQL questions, overall around 10-15 minutes. Received an offer a couple of days after. The whole process was clean, friendly, and fast at every level.
