Worldwide Recruitment Solutions interview questions

Got invited for an interview - the first email personnel I corresponded with was a bit bland, and a tad rude - probably a very poor choice of words when I was inquiring about being on the interview (there had been certain issues joining the session). Anyway, I managed to secure the initial interview with a lady, which was good. Then, got invited for another interview with someone from the tech department. However, never heard of them for weeks. I did ask for a follow-up multiple times, but nothing came back - I really find this kind of behavior unprofessional. I don't mind being rejected or coming short of what they are looking for, but not responding to multiple follow-ups regarding an application status says a lot about the company and its employee calibration. It can easily reflect on how they treat their current employees already.
