Lufthansa Group interview questions

Three weeks after submitting my application, I received a call from HR for an initial screening, where they asked basic questions and reviewed my past experience. Two weeks later, HR contacted me again to schedule a skills assessment with the Product Manager (PM) and Product Owner (PO). Unfortunately, I did not progress to the subsequent team fit assessment stage.

Got rejected without feedback. Passed all digital assessment and came in the top 3, still rejected without feedback after a did a very short,general interview. Left confused. It is what it is.
