Test engineer 1- Aurora, CO

Quick question for anyone that has an direct experience or knew someone that held a position as a Test engineer for Raytheon. The job description is pretty general, and would like to know a little more information about what a test engineer really does there.

It says that one will be testing Unix and windows based systems, and develop automated test scripts.

Seems like an interesting job to me. I will be interviewing for a position later this week, and was just wanted more insight before I walked in only knowing the description online. I understand there is only so much one can say about it. Just wanted to know if it actually is an interesting job, how demanding is it, and is there a carrer path, and be able to move forward from the entry level position later down the road.
