I couldn't feel anything at all.

I first received a proactive interview invitation from the company on 104. Although I took a look at Jobmentors and got the impression that it might be a bit demanding, I still thought it would be worth giving the interview a try, so I replied that I was willing to accept the invitation... But I never expected to be left on read immediately. Later, when I asked again whether there was an opportunity for an interview, they also simply left my message on read. That was extremely disrespectful—not even a reply. Is this the level of conduct your company stands for?
