Vay (Germany) interview questions

I recently completed a four-stage interview process for a role where I felt I performed strongly. I passed the initial screening, had a positive one-hour discussion with the team manager, successfully navigated a technical interview where I explained complex topics and showcased my project leadership (including delivering ahead of deadline), and finished with a final team meeting. A week later, I was rejected with the feedback that my knowledge was 'weak' in specific areas I was never questioned on. This was particularly confusing because I had confidently addressed the technical subjects that were discussed. Reflecting on the process, a comment from the team manager now stands out: 'The team must like you.' This suggests the decision was ultimately subjective, based on personal rapport rather than an objective assessment of my skills or proven accomplishments. It seems I was evaluated on a hidden criterion team consensus on 'likability' that wasn't part of the stated job requirements.

That was really a good interview and I would make it to the next stage of interviews! Unfortunately, I only received a rejection email with no reason given. I have asked them to let me know what they thought, but they still haven't responded!
