ACI Federal interview questions

Was a strange experience overall and is somewhat shocking and disappointing given the work they do under a segment of their business is staff augmentation. I was contacted by a recruiter via text, and I responded, then I was ghosted for several weeks, then a different recruiter reached out with a strange name and we scheduled a phone interview where I was told to call the hiring manager on his cell (very unaccustomed to this and it's generally not good practice), then subsequently invited to an in person interview with another person. A day or two later I received an email from a recruiter saying how well my interview went and how excited they were about talking with me. She also said that they are finishing up interviews and would get back to me on next steps and I never heard back. It's been WEEKS! Not a great experience, not a good look for them either.
