Deverus interview questions

Applied online. A week later I took a 30 minute cognitive assessment. A week after that they called me in for an interview the following day. Their Austin office is in a house, and nobody came to the door to let me in for about 20 minutes. Once I finally made my way in to meet with the operations manager, she sat there in front of her laptop during our interview doing work. I took offense to this; at this point I have contributed a decent amount of my personal time to this role and felt like I was inconveniencing her in the interview. Additionally, the individual that I met with and the gentleman colleague that joined her were partaking in talking negatively about their coworkers to me and making inappropriate jokes. They also told me that he girl who had this position before me was lazy and was fired. Pretty bad interview, but it gets worse. They asked me if I could start Monday, I said of course. The last question they asked me was my salary range, and then I was ghosted and never heard from again (even after an email simply asking for an update regarding my candidacy or if they had moved in a different direction). Could have saved us all a lot of time if they would have asked pertinent information at the beginning of the process. Rude, unprofessional, and a waste of time. RUN.
