I was interviewing at the Constellation Tech Hub / BCA Europe in Coimbra, Portugal. I had 3 interviews, along with an HR interview, and also a case study. All interviews went well, and each time the hr calls to set the next interview, but after the last interview, things changed dramatically. I was promised to have an answer next Monday or Tuesday, either way, but that didn't happen. When I called to check on Friday, I got no response, only a message saying that I will be contacted next Monday, and even if, that didn't happen until I tried to call again, only then I received such an email.
