Revolut Sr Software Engineer interview questions

I was reached by a recruiter over linkedIn and then first HR round was scheduled. HR had some questions written and asked them. Once I cleared it 1st round of discussion was scheduled with 2 interviewer, in which this asked to write a java problem and their unit test. I covered all the scenario and it went well. After that I keep on following with HR for 2 week with the feedback and heard nothing back. And after 4 week got a rejection mail from HR with my feedback which does not align with my interview. Seems they just want to waste your time and nothing else.
