GECU interview questions

My first (and only) interview was with a panel of 4 managers. After meeting with them for about an hour, I was advised I would need to complete a practical exercise and would be given 20 minutes to complete the assignment. I was lead to another area and given the assignment at a semi-private computer. Once completed, I was informed they would be in contact with me. After a week or so, I reached out to inquire on the status for making their decision. I was advised again that they would be in touch. I reached out again two weeks later to inquire and was given the same generic sentence. At the 4 week mark, I was sent a rejection email.
