Equifax Consumer Relations Agent interview questions

The whole process took almost a month. First was a phone screening with an HR. I was then passed to someone else handling my application. Got an email 2-3 days later to ask me for my available days for the next process, a video interview with the Hiring Manager. Gave her my availabilities but she did not tell me when the interview would be, only the process on how to get in the video interview. I got an email 2 days after that just said video interview at 12:30pm on the same day as the email. Regardless, I did the interview. I never received any update nor any answer from the person handling my application. 2 weeks later I emailed the HR and even then there was no answer. I got a generic email at 3 am about my application being rejected. Say the least it's very unprofessional.
