PGTEK interview questions

I was cold emailed about the position and headhunted by management. That person arranged an interview with the department manager the following Monday. I was told by the manager during the interview that they will arrange a technical interview with their team of engineers. I have heard nothing for two weeks. Chased it up with both contacts within company only to be ghosted by them. Very unprofessional. This is an indicative of how the company treat their candidates then it is not a company I want to work for.
