Portify (United Kingdom) interview questions

phone interview, they mentioned about next steps, didn't hear from them for a few days. Straight after the phone that is when it became unprofessional. I waited few days then saw their email on a monday where they provided email about next steps, but it was like they wanted an instant response, received response on a tuesday that they were no longer interested in proceeding further, what a way to mess me around.
