Brightline Interactive interview questions

Responded quickly, set up interview fast with some devs, they were all friendly and great. Progressed to the second interview, once they time came- nobody showed up. Emailed to inquire about whats going on, got one response asking if anyone showed up, and then was completely ghosted. New person pops on their linkedin for the position soon after. Completely unnecessary and unprofessional. Not hard to just say you went with someone else. Why even set up a second interview?
