Siemens Developer interview questions

The round started with the introduction. Then the Interviewer asked me thoroughly about my projects. There was a brief discussion about one of my projects. Then he started asking me basic DSA questions with an array, linked list, etc. He asked me which Data Structure I preferred and there were questions about that. He then asked me some of the puzzles which you can find on Geeks for Geeks. And then that's it. They asked me if I had any questions.
