1904Labs Full Stack Developer interview questions

I did the introduction interview, HR interview, and video screen. Everything seemed to be going great: I felt I did well and liked everyone I talked to. Then nothing. I sent an inquiry email and never received a response back. The experience was pretty disappointing. Taking multiple stretches of time off from work only to be ghosted left me with a bad taste in my mouth. A simple "no thanks" or "not a good fit" would have been appreciated.
