I applied online. I interviewed at Revolut (Kraków) in Dec 2024
Interview
First - screening, 15 minutes on video chat, the interviewer asked me if I know SQL, I knew, so I passed. The second interview was live coding, I had to write a SQL query and come up with some simple „metrics” for measuring stuff like the success of a new bank program or checking if a transaction is a fraud. The final stage was behavioral with the hiring manager; it was more like a vibe check.
Interview questions [1]
Question 1
Given our database with transactions and clients, what metric would you apply to check if a transaction is fraudulent?
