If at any interview you were told you are overqualified, simply tell them it is to the advantage of the recruiting coy. That it shows your learning exposure. Such questions are not posed to put you down rather what you have to offer with great exposure as the qualification presupposes.
If you are scared that your 'intellectual progress' would put you down, then don't include it in your CV. But I tell you that would be a bad advice. My mentor once told me that "if you must go for something worthwhile, then bring your best foot forward".
We are just scared for nothing! Worldwide , a second degree is advantageous even when it is not relevant. Why? Because it simply shows you are ahead.
The problem is that we just want a job that will put food on our table. Remember one fact of employment- being in the employ of any company can never make you rich until you have a plan for yourself. Like I use to say " nothing gets better in life unless you first get better" And getting better you have to keep learning.
