SAP Labs Interview Experience | On-Campus | SAP Basis Consultant
I participated in SAP Labs' 2025 placement drive at Pune Institute of Computer Technology (PICT) for the SAP Basis Consultant role. The process included three rounds: an aptitude + CS fundamentals test, a group discussion (GD), and a technical + HR interview. In the GD, I confidently initiated the discussion on "Being Famous vs Being Knowledgeable," supporting my points with examples. During the interview, I discussed my resume, internship experience with Node.js, PostgreSQL, and Prisma ORM, and machine learning models like Random Forest Regression. I also explained my problem-solving approach and adaptability to new technologies. I was one of the five students selected, and it was a great learning experience. My advice to future aspirants: Be thorough with your resume, practice aptitude and CS fundamentals, and work on communication skills. #Experiences #interviewexperiences #Experiences-QnA
