Siemens Software Engineer(Internship) interview questions

I met the recruiter at a school job fair. However, there was process involved with applying online. Later got a phone call to schedule an in-person interview. What was supposed to be an hour long interview took hour and a half because the interviewer and I got along. Talked about how I would learn from scratch since Siemens uses proprietary languages, workflow, etc.

First was phone interview HR behavioral questions, then phone interview technical questions about general computer science concept questions and a linear algebra question. Then on site technical/behavioral interview. They asked about stuff on my resume and then asked me coding questions
