University Loft Company interview questions

Was brought in after a short phone interview for a second interview. At my onsite interview they managed to talk the whole time and never asked a single question about me. After about five minutes, the hiring manager took a phone call, walked out, and I never saw him again. Having been through several different interview processes, I thought the whole thing was very odd. They extended me an offer and they retracted it days later without ever notifying me that they were doing so. Overall, the experience as a whole was very unprofessional. I’ve since moved on and am much happier than I would’ve been, but I still think it’s important for potential candidates to know the low level of professionalism that they will be working with here.
