Public Consulting Group Summer Program Coordinator interview questions

I had an initial screening phone call which asked questions pertaining to the job post I answered. The job description was very broad and included Program Management, Program Matching, Recruiting and Marketing. I was under the impression this was a job doing professional development for teachers over the summer, but when I got to the second level interview, I found out it was actually assisting with summer camps. Now where in the job listing is this mentioned, I felt misled.
