They interviewed me for 2 rounds 1st round introduction with HR 1st technical round with team leader For 2nd round they called me to Darmstadt from Munich and said it's just a informal catch-up with team and not a technical or managerial round. After I went back , sent me a reject after 2 days with no reason provided. Did not even reimburse the travel expenses for visiting for the interview process. The catch-up could had been done on video call also if they were not sure if hiring or not.
