Siemens Field Service Engineer interview questions

HR and HM interview then technical interview with the engineer, finally external interview with a scenario based situation. Did not understand what's the point of the third round but they decided to go ahead with another candidate after that one.

Interviewers were 3 hiring managers and 2 operations managers. Mostly job related questions. Every questions was related to my resume information and the job post. It was about 2.5 hrs long.
