Siemens Digital Industries Software Software Engineer interview questions

Interview with a simple test to test systematic checking abilities. Nice calm atmosphere with a to the point interview. They asked questions about my relevant experience with doing things similar to the role and things I mentioned on my CV. They also asked me about what I knew about Siemens PLM and about projects I had done prior.

A few days after applying, I received a request for a 45 min phone interview where I talked about the projects I worked on and answered technical questions on mostly C++. This was followed by an on-site interview two weeks later where I met the manager and a few members of the team. After a brief tour around the office, I stayed in a single room where members of the team came in one at a time to interview me. I had the impression that the manager did not want to be at my interview at all and mentioned several times he had somewhere else to be. When he asked if I had any questions, he impatiently told me to not waste time asking questions for the sake of asking questions. Other than that, I talked to two other team members who asked about my previous work and more programming questions. One person was friendly, the other I felt had a smug attitude if you did not know something or answered wrongly.
