Computer Aided Technology Order Management Associate interview questions

CATI was a very poor interview experience. To start - This general "Order Management Associate" role would contain 4 interviews which (in my opinion) is very excessive for a CSR focused type of role. They explained the process would include an initial screening, a manager interview, a peer interview, and a COO interview at the end. Excessive, but I went along. So after the initial phone screen where the recruiter expressed interest, she had me take a series of tests called WONSCORE. This was actually not disclosed when I initially asked about steps in their process but I went along with it and took the 45 minute series of tests for them. Thought I did fine on it but apparently not. Had not heard anything back (radio silence now despite me completing this right away - this would soon become a characteristic from them) so I messaged recruiter and she told me hiring team was busy that week and she would get back with me soon. Okay, sure. The next week I get an auto reject reply from her telling me thank you for applying but sorry we are not interested. I simply asked her for a little more feedback and if it was a certain part of the WONSCORE test that caused me to fail in moving forward so I know what happened - because prior to that she expressed interest in moving me on to the manager. But instead she and another associate simply ghosted me. Very unprofessional. I can accept not moving forward if they didn't like something about my tests (again not disclosed when I first asked about their process) but to simply ghost me when I ask for a little more context is unprofessional to the time I spent for them and is the very reason they are now getting a negative review. I felt a clear lack of respect. If you can't go into more detail fine, I could have accepted that but don't ignore me. My advice for them would be to show a little more respect to the people who take the time to apply to their company and learn about the company and to not ghost them when they ask for a little bit of feedback in a constructive way. My other advice would be to simplify the interview process because 4 interviews plus an undisclosed personality test is very excessive for a CSR type of role compared to what I have seen in the industry. This was a very poor experience for me.
