Siemens Software Developer interview questions

It was a pathetic interview process. Reporting time was 8.30 a.m , but the HR himself reported after 1 hour i.e 9.30 a.m. The entire office is highly secured, even washroom access area also required Siemens badge to be displayed. Coming to the employees and the HR, everything was so unprofessional, they used their native language Marathi to communicate. I had given interviews at numerous companies in Pune, but never saw such discrimination, HR are meant to be polite and soft spoken, I could hardly find the HR smiling or showing positivity. Coming to the interview, there was a 45 minutes online test followed by technical discussion, I was highly surprised to see the technical interviewer asking the very first question to me was what's the name of your college, where are you from basically..? I mean why does an interviewer has to judge me on the basis of my hometown or why would that bother him so much that I belonged to which place. Honestly speaking I already had 3 offers in hand, but due to Siemens' reputation I had gone to give interview and the level of difficulty of the questions and the types of questions were exactly the same as asked to me in other companies' interview. But there was definitely some attitude problem of the interviewer, some sort of superiority complex that he was a Marathi, that even after myself getting satisfied with the types of answers given , he was not convinced and rejected me. Anyone going to Siemens, kindly note be ready to face unprofessionalism and attitude issues
