CalAmp Field Applications Engineer interview questions

Got the initial contact requesting a phone screening with an HR rep. That went fine and easy as it was mostly just the basic screening questions. Got pushed forward to have an interview with one of the IT directors of the company over a web call. That interview went great; was answering all questions given just fine. Barely any technical questions, just more “industry knowledge” type of questions (i.e. do you know shell commands, APIs, etc). At the end, the director even claimed they thought I’d be a great fit and mentioned they’d be moving me forward. However, a week goes by and nothing from the company. I decide to wait just 2 more days before checking in. By the next day, I received an email claiming I’m no longer being considered. Seems strange given the fact that I was told I seemed like an excellent fit and would be moved forward?? I understand if the company found a better candidate, but to have decided without having me go through the ACTUAL technical interview seems a bit unfair. Oh well, just be careful with this company even if it seems like your interview is going well.
