SAP Developer interview questions

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.
