Siemens Software Engineer Internship interview questions

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

I applied through college in mid-February. Got a phone interview in late March. The phone interview was 30 minutes. The recruiter introduced their projects available and asked about things on my resume. The recruiter was very nice, but then he only informed me of the interview 4 hours ahead of time. And I did not see the email and did not know about the interview until he actually called. I had to asked him to call back 1.5 hours later (when I could be better prepared). The interview was not very hard though. And then got a group/panel interview at their local branch in late April. Met 4 people on the team, got asked questions about my previous experience, my resume, some behavioral questions, my interests, and plans after graduation. The people on the team were all very nice and friendly. Got the offer about one week after the group/panel interview.
