Until this company hires someone that behaves professionally I don't think it's worth pursuing. They are classic "ghoster's". You will be told you did great in the interview and a follow up will be suggested. But you will never hear from them again. This is not only offensive and unprofessional, but potentially reflective of the culture in the company. I don't know if anyone from their HR organization reads these posts, or even any other executives in the company. But they need to take a serious look at their company recruiter in the US.
