There appears to be an assumption that this is a linear rating list. Have you asked how the ratings were derived? Second, it appeared if your rating was based purely on your perception of the first week your score would be higher. As usually the first impression is important. I find your comment: From my perspective this job is really easy, so I'm confused. Did you ever think they gave you easy stuff to see how you reacted? If it was easy did you make sure what you did was extra perfect (documented, tested etc, good grammar?) If it was so easy, then an above average person would have asked for more work, or more challenging work. Lastly, they just hired you. They expected you to perform at level X. Had you been rated a 7/7 then maybe they hired you at too low of a level. If you were a 1/7 then you were hired way above your skill set. A 4/7 says you are a perfect fit for the job they hired you into.
