Hanover Research Research Associate interview questions

1) Applied to Hanover in early June 2) Completed an hour-long, online GRE-type test (nothing too difficult) 3) Spoke to recruiter on the phone for 30 minutes. She informed me that she would send me a mock project to complete. 4) Spent a week (probably 40 hours) working on a report about international branch campuses. Guidelines were vague but I assumed they were more interested in seeing my writing quality. 5) I was informed that I would hear back about the project in 4-10 days. Ten days passed and no word. I emailed Hanover and they informed me they received positive feedback on my project. 6) Scheduled an in-person interview in Washington, DC. Interviewed with 3 project managers. The interview lasted two hours, and my perception was that the interview went well. 7) Returned home to an email saying the feedback from the interview was positive but that they wanted me to complete ANOTHER project. ---- Here is where I should have said no. At this point, the fact that they used me to complete another project is really insulting. 8) Completed a three-day data analysis project. I was informed I would hear back in 4-10 days. Surprise, surprise, 10 days came and went and no word about the project. 9) A few weeks later, I received an email saying Hanover was busy with employee evaluations, and they hadn't had a chance to review my second project. 10) On August 25th, (remember I applied on June 4th), I received a rejection email with no explanation as to why I was not chosen for the position. I have never had such a terrible experience with a company before. I am just disgusted that Hanover has the audacity to treat its candidates like this. If this is how this company treats its candidates, how does it treat its clients? I wouldn't want to work for this company nor would I want to do business for this company.
