Devyce Senior Frontend Developer interview questions

Had an interview at Devyce. It consisted of 1. Technical Interview - Systems Design Style 2. A small-ish take-home assignment to go around their platform and prepare some suggestions on how it can be improved 3. A chat with the CTO of the company Overall interview went pretty well and I was under the impression that I'd probably get the job. At the end, they asked what my desired salary was and I asked for a salary within their advertised range. They refused and then ghosted me, no negotiation, nothing. A completely unprofessional behaviour and waste of my time. I do not recommend to interview here.
