SAP Associate Software Engineer Developer interview questions

First round is online test, this round was held online on the Hackerrank platform. The duration of the round was 75 minutes. * It contained 25 technical aptitude questions and 2 coding questions. Majority of the questions were on C, C++, and Java with few of them from data structures and algorithms and their complexity. * The coding questions were not the same for all who took the test. and 2 Technical interviews(F2F) followed by Managerial and HR Round. Interviewer was very friendly , they went through my resume and asked about my project and help me to find a way to improvise it . Most of my questions were related to Java(Basics) and C programming.

The interview started with the interviewer greeting me and asking me whether I've had my breakfast and how my day was, which made me comfortable. Then we moved on to my projects and details about it. Then he gave me a clustering based question, which I answered well, but the interviewer was not at all convinced, even though the answer was right. He was looking at his phone and was least interested in the interview. Totally unprofessional and disappointing
