Revolut Product Designer interview questions

The recruiter explained to me the process was divided into 5 steps. 1. Phone screen with a recruiter. 2. Portfolio review from the team. 3. Portfolio presentation with a Revolut designer. 4. Design Challenge (take-home exercise) 5. Design challenge presentation on-site.

I applied for the senior product designer in Revolut in October 2019 and I passed 2 rounds of design interviews and passed the design home task. But finally failed in the last interview with a Product Owner. The rejected reason was super ridiculous. He thought I don’t have experience working with developers. I totally have no idea how he came out of this conclusion. If I don't have experience working with developers or I'm not able to work with developers, I couldn't have been working in the UX design field for so many years, and how I made so many designs I've done launched online? I passed the design interviews and the home task which took me a lot of time. They confirmed and recognized my UI and UX ability but used an untrue thing to reject me. So I really question the professionalism and fairness in making the final decision of my application, or maybe it was the decision just from that PO. He is not even a designer. He made the rejection decision from a personal point of view, but not from a professional point of view. He doesn't like me, kept challenging me during the interview. He misunderstood what I said in the interview then I kept explaining to him. Finally, he used a totally untrue thing to reject me. I’m so disappointed at Revolut and their interview policy.
