I am an EO applying for HEO roles.

I applied for a HEO role which I believed I hit the criteria very well. I had multiple people who are grades above me and external people check my personal statement and they didn’t ask me to improve it but it only got marked a 3 and I didn’t get an interview. I’m looking to improve my personal statement but I’m not sure how to? I’m looking for help and advice please?

I don’t want to post my personal statement on here as it’s quite specific to my roles and achievements but happy to send privately?
