Siemens Manager interview questions

Interview is at multiple levels with moderate difficult level. Interview process is lengthy and time consuming. Not easy to enter into Siemens. Negotiations are bit tough. Work culture is good but less salary. Need higher knowledge level for pass through the interview process. The interview experience is great.

Got a reply a week after cv submission and the first (remote) interview went very much according to normal procedure (background, ambitions, skills, salary) after which the interview feedback would be transferred to the hiring manager. From then on things went into a black hole. Because of holidays, the application seems to have evaporated. After four weeks HR still hadn't received any feedback from the hiring manager. I checked again and the file hadn't gotten any follow up. Very strange how a company that sells automation to customer isn't capable of having a proper follow up of its candidates. Two months after initial interview still no feedback.
