Siemens Mobility interview questions

Good interview with heads of all departments and the overall head. Some technical questions. Some questions about CV. Some general conversation about myself. Low pressure environment. Given a tour of the facility. Allowed to talk to current employees with no oversight.

It was a long process that took nearly 3 months. The recruiter reached out to me after 2 months of application and there was 2 levels after that lasted around 1.5 months. The total interview process was included a hiring manager review and technical session at london office. Both went well and the manager promised to give a callback within 1 week. But they ghosted me after the whole process without updating about the outcome. I always thought siemens as a company with integrity but turned out a disappointing one.
