Revolut Financial Crime Analyst interview questions

After the first 20/30 minutes call with HR, I did not received any feedback for 15 days. So, I sent an email asking for any feedback and they confirmed that they wanted to schedule a second interview, which I did. Long story short, more than a month has passed and even though I sent 2-3 different emails asking for a follow-up they have given me no updates. I understand that there might be months with extra workload, but as a company you should keep in mind that candidates' time is valuable too and that most of them have given extra effort in preparing for the interviews, so the least an employer could do is given a feedback (good or bad).
