Richmond Marketing interview questions

The interview process was quite quick had initial call with the recruiter and then a video call with the hiring manager I believe and then on to in person interview which we had to present a case study

They moved fast but in doing so only gave 3 days to pull together a full creative proposal for the brand. The interview went really well and I had put a lot of work into it on top of working my own job. They said they were extremely impressed and would be in touch quickly. I presumed I had the job because of their feedback but then the recruiter said they said no. I asked him to go back and ask for feedback and they literally came back with nothing. All very misleading and confusing.
