Casco Publications interview questions

I applied for a freelancer role but they got back to me after a month and asked me if I was interested in a full time role, of which I wasn’t. Because I was already working full time elsewhere. Told me that they were always looking for freelancers and would love to arrange a face to face to see my portfolio and a short interview with the bosses. But they ghosted me and didn’t get back to me at all after I sent my available dates and time. Felt really unprofessional. Would not recommend.
