Volkswagen Group Engineer interview questions

There were three interviews: the first one was a pre interview with HR Department (Pre-Screening) The Second one was with the hiring manager. The third one was with the hiring manager with other managers and team members.

After videocall they invite you for a personal meeting and give you the chance to see everything in person. You are presented with an excersice which you need to fulfill. Then they didn't even call back. Very rude behaviour
