SAP Software Engineer interview questions

5 stages interviews went on very good in the initial rounds and got tougher and tougher as it progressed which made me think i should leave the place without informing anyone in the team or the hr department. i had no toher option to attend the full interview process and left the place. but i was selected at the end but i rejected the offer right away.

The interview takes from 1:00 pm to 7:00 pm. 3 Rounds (1:1) + 1 written test. All questions in interviews are coding related. Question is quite easy, except the question in last round of interview. It need you to implement an algorithm in a PC, and make the code runnable. (in VC++ 2010)
