BTI360 Mid level Software Engineer interview questions

Lies about their requirements. Started off with a recruiter for a quick 15 minute conversation about the position. Had an in person interview scheduled for a week after pending security clearance approval, which I do have. Supposedly should take two hours. Since this requires a secret clearance, needed to meet with a security clearance specialist. An hour later, got a random email that everything was cancelled. No notice, no reason, nothing - just a condescending answer that "requirements has changed." Just horrible and a waste of time, shameful since process had glowing reviews here so was looking forward to it.
