MTS Systems Technical Writer interview questions

This company could stand to reevaluate their interviewing process. They put me through two 30 minute phone screens, a 2 hour in person interview and a 3 hour in person interview. I was continually asked the same questions and praised as an excellent candidate. They very much made it seem like they were set on hiring me. Yet, I still hadn't received a job offer days after my 4th interview. I politely inquired about when I could expect a decision from them and mentioned that I had another job offer on the line. Inexplicably, my having another job offer led to them eliminating me from the running. That didn't feel like a very fair decision. All in all, this was a frustrating experience.
