Hibu Customer Service Representative interview questions

The interview process was the absolute worst I have ever experienced. There were a series of several lengthy tests. After that, was an interview with 5 people, including three managers of the department. All of them were in the the room with me at the same time, alternating their questions like a firing squad. The department managers were cold and impersonal. The total interview process took approximately 4.5 hours without an offer for a break in between at least 3 lengthy tests and the actual interview questions. Communication prior to the interview did convey their process or length of time to be at the interview. All of this for an extremely low-level, low-paying job.
