I got the Problem Solving Interview as the first step because the Hiring Manger was not available. The question was: how would you improve sales for Revolut. That's it. Completely not related to my experience or the role I applied for. I was supposed to ask questions to the interviewer as per Recruiter's instructions, but every question I asked was not really answered. The Interviewer only wanted to hear my solutions, wasn't really cooperating. I did my best, I really had a feeling that even though this interviewing style was crazy, I came up with many ideas. But I got rejected, asked for the feedback but never got one.
