Unprofessional behave - Mitarbeiter (anonym) bei RIKAS: Mitarbeiterbewertung

I completed multiple job interviews for this company, however when I asked some updates about the recruiting process, they simply disappeared. A transparent feedback would be appreciated, even when negative, because people put plans and hopes. I sent multiple messages for follow up because, at the same time, I received other offers from different companies, so it was even more important to get a response in order to make a clear decision. But, no one even bother to reply me. Simply UNPROFESSIONAL
