Revolut Operations Manager interview questions

This is for Operations Manger (Process) in London). I had a hiring interview where the basic past experience questions were asked. For next round they had given me a home task which needed a lot of work to be done: to build an entire process workflow in JIRA, document on Confluence and a lot of detailed Excel-based problem solving and advanced query writing. I put a lot of thought into the entire task and built on it. After submitting the PDF, I got a rejection email the next day saying the ‘Hiring Managers have determined that the home task didn’t fully align with our current needs’. Felt quite abrupt and cheated to be very honest, especially without a call to discuss or some feedback
