Liberty Mutual Insurance Customer Service Representative (CSR) interview questions

I applied online and received an email to set up a phone interview within a couple of weeks. The phone interview was easy and structured. It consisted of six or so typical behavioral questions. After the phone interview was completed, the interviewee told me she wanted to move me on to their face-to-face process. The incredibly tedious process was a four-hour experience. It began with a computer test that tested my skills at processing processing phone calls (it was very easy if you have common sense). The next test was a behavior/skills test (that I had already taken online...), which was also simple. I then had two back-to-back interviews that consisted of a ridiculous amount of behavioral questions (at least 15-20 in total). The questions weren't exceedingly difficult...pretty typical behavioral questions. Finally, I spent about 30 minutes watching an employee process incoming calls in her cubical. I tried to ask some questions about the job and the day-to-day experience, but she was on the phone for all of 3 minutes that I was there. I was told I would be contacted within the next few days. Two weeks later, I received an email rejection letter. I believe I seemed too ambitious to move up within the company and the call center manager didn't want to deal with hiring me and then having to replace me 6 months to a year down the road. They were looking for call center enthusiasts.
