Siemens Digital Industries Software interview questions

Quick, fair interview. some of the technical questions were not easy... some where not related to programming (thought the position was), but more about physics. The interview process was done in one day for a few hours - met a few interviewers.

The hiring process started with PPT followed by a pen and paper-based test, that included Data Structure, Digital Electronics, and aptitude questions. The questions were subjective and all sections were to be attempted. The result was declared next day. There were 3 rounds of the interview. There were two rounds of technical interview and an HR interview. The technical interview was base on data structures- array, linked list, tree traversal, and graph. They were also asking puzzles.
