Not so much a problem about the interview, but being ghosted. I left voicemail, emails and called on numerous occasions so finally chased the HR manager through LinkedIn. They denied ghosting candidates and that would never do so despite doing that exact thing. I then received an array of excuses that out of four managers, not one could drop an email or make a quick call. Speaks volumes about the potential culture and, in my eyes, destroys expectations and damages a brand name.
