Barclays Full Stack Developer interview questions

Walk in interview. I was selected for both FSD - BA4 and AVP titles. I prepared for both roles. But on arriving they said it must be a mistake and that someone with my experience level cannot be considered for AVP role. I gave a technical test for both roles before getting accepted for the F2F round. Couldn't they have just ignored my application to the AVP role if that's the case? Dissappointing interview process, especially since I had to travel to Pune from Mumbai.
