Jacquard interview questions

I interviewed at Phrasee in December-January through a recruiter. After an initial stage, I was asked to do a technical assessment (full-stack app, including frontend and backend). After sending it back to them, the recruiter informed me that all the candidates were rejected and they didn't provide any individual feedback. I reached out to one of the interviewers for individual feedback but I was ignored. Looking at a previous review of another candidate, it seems that they closed the position. In the current situation with loads of layoffs and the market being so competitive, asking for a full-stack app and not even providing feedback is very unprofessional, and a big red flag.
