As the title suggests, I have a Masters in my field and a relatively unrelated Bachelors degree. A-levels are the exams you take here in the UK in order to get into University in the first place, and being fully honest I did not do well in these (I have 2 full ones, and 2 halves, equivalent to a B,C,C grade) and they are all unrelated to my current field.
Since I finished my Masters Degree, I've not been asked once in three different rounds of looking for new roles about my A-level results. Now I've started looking again, and one of the companies a recruiter put me forward to has come back asking for those results. I don't include them because I have limited space and they are unrelated.
My personal opinion of this is very very low. I have two degrees, and a higher level of education than a high percentage of the people I would be interviewing with. I could understand it if I only had a Bachelors, but frankly I think the two highest levels of education is all that is necessary for an employer to know. As I mentioned before my results were not great, and I understand that this company is asking for them on some basis of "consistent high level of academic achievement" or some such.
I am aware that my results at that level may be affecting my viewpoint on this, but I feel justified in stating that out of principle I will be withdrawing from their process for having asked for these results. I do not mind disclosing the results, but as above I think it is actually quite rude, implying I have a Mickey Mouse education.
How do I deal with this in line with my principles, whilst maintaining professionalism? Should I just state that I am withdrawing from the process with no further explanation needed?
P.S. I'm not concerned about any future relationship with the company that the job listing was for, after they asked about this, but it would probably be unwise to get on a recruiter blacklist
