My work experience is structured as follows:

• 2013-2014 Junior Business Manager, ABC Company (large)
• 2012-2013 Business Associate, ABC Company
• 2012-2012 Internship, DEF Company (major Fortune 500)
• 2006-2009 Business Manager, XYZ Company (small)
• 2004-2006 Business Assistant, KLM Organization (medium)
• 2002-2004 Business Freelancer

*Let's imagine "Business" could mean any business unit, Marketing, Sales, Finance, IT... and my experience was always in the same or similar unit (e.g. Marketing and Sales).

My experience with job searching is that ever since I did my degree and my internship, I find it more difficult to be called for management-level job interviews (although I have previously been in management roles). This makes me wonder whether the fact that I studied and did an internship (non-management role) makes recruiters think that I am not management material, or that my "true" experience is only what I gained after university.

Do you think this could be a possibility, and if yes how could I mitigate it?
