Siemens Energy Manufacturing Process Engineer interview questions

Would not recommend going through the hassle. Between screenings, panels, onsite visit, I went through about 5 different interviews and countless phone calls over the course of 2 months. Finally got an offer after being patient, and was rushed to respond to it. I tried to negotiate but was immediately shut down; no room for any conversation and caught rude comments for even attempting. Regardless, I was still considering the role and I wanted to use a little more time to think it over. Offer letter stated I had 5 business days before it expired. Company did not honor what was in writing and revoked my offer just hours after I tried to negotiate. Big lack of respect, trust, and patience. Quite unprofessional in my experience.
