I was on several interview teams in Idaho, and letters of recommendation did not really have anything to do with who we picked for the job. We looked more at their resume and interview. The interview was the final decision for us most times. The only thing I remember noticing is that one of the women who interviewed for my job had worked in our district a year or two before, but did not have any recommendations from anyone in the district. That caught our attention and we thought it was a little strange. I agree with highlighting the positives in the letter.
