Siemens Software Development Engineer interview questions

We had an Online test which had around 30-40 medium apti questions, We were a total of 35 out of which only 17 were selected for Technical interview. After the technical interview, 10 were rejected and only 7 were left; I was one of them. And then we had HR round. The cutoff for this company was 6 CGPA. But, during the HR round, HR directly sends a guy saying that Siemens recruits students with only CGPA above 7. They should have mentioned this before the Online test or at least during the technical interview. Then the HR selected only two guys out of 7 whose CGPA was above 7.5. I hadn't expected this from a company of such caliber.
