If I were interviewing her I would have simply said yes you are absolutely right and over qualified which is why unfortunately we are not offering you the role, thank you for your time (let's face it with that attitude in an interview what would they be like in the job)!Added to that is a lot of students are doing useless degrees that will not get them good jobs and the universities set students up with unrealistic expectations.
A few years back I had a woman (fresh out of university) with an MBA apply for a job that did not need an MBA and was a trainee role. She argued about the "trainee" salary because she had an MBA and felt that she should be paid a lot more. I agreed and told her that she could have the MBA salary but that we'd deduct training costs which would bring her back to the trainee salary............. she got the point....
