NJM Insurance First Notice Representative - Part Time interview questions

I applied online and was contacted for an initial phone screening. After the phone screening I was asked to come in for an in person interview. I met with a recruiter and took a typing speed test. After that I was contacted for a second interview. The second interview was with a hiring manager and what seemed to be someone in training. The interview felt much more like an interrogation versus an actual interview. The woman who interviewd me was rude and unprofessional. After that I was told I would hear back soon. Weeks passed and I didn't hear a thing so I emailed the hiring manager and never heard back, after another week passed I called the office and was told someone would call me right back. No one got back to me. Finally weeks after that I was told that I was still being considered and they would let me know if my status changed. I have never been through such an unprofessional hiring process. Everything from their demeanor to the decision was handled poorly. Even if offered the position I would decline since they don't even have their HR staff together.
