SAP Developer Senior interview questions

There are 5 rounds 1-1 interviews. 4 algorithm white board question, one project you did related questions and behavior questions. The interviewers are very unprofessional. I wrote the algorithm on the white board, but the ridiculous is that one interviewer didn't understand your solution at all even with explanation. Another one did not exactly understand the answer, and insisted that the answer is not right. I am so disappointed at the interview experience at SAP Palo Alto. Even they gave me offer, I would reject it. The reason I don't want to work with this kind of team members that are not nice, not capable and not professional.

The Hiring Process was straight forward. HR contacted me and fixed a date for scheduled interview. Interview started on time and the result was also communicated by the HR over there only since I did not clear the interview.
