Domande di colloquio per .NET Developer presso Fujitsu

I had interview with Fujitsu for their team in Toronto. I spoke with the team lead and the manager. They mentioned that they would let me know the result Next week, but guess what? I didn't hear a single thing! So, I decided to send an email to the HR who set up the interview, but unfortunately, I didn't receive any response. I also tried reaching out to the recruiter, but I didn't get a reply either. I have to say, this whole experience with Fujitsu has been extremely unprofessional. How can they waste my time and not even bother themselves to send a simple email with a rejection? It's just plain ridiculous!
