Texecom interview questions

I interviewed for the Marketing Assistant role at the end of may. The interview with the Head of Marketing went well, and I was told I’d hear back by the first week of June. That never happened. I followed up twice via email and even reached out to him on LinkedIn, still no reply at all. Just complete silence and ignorance. It doesn’t take much to send a quick update or at least a courtesy message. This really does reflect how they handle things. If this is how they treat candidates, I’d be worried about how they treat employees. Highly disappointing and unprofessional.
