It's complicated. I was in the military, have some significant background there, and I changed careers a few times. The CV is, and I honestly say this humbly I am not trying to brag, very good I think, potentially exceptional, but I do not know how to market it, let alone find someone in the UK who could interpret the vagaries of the military portion.
I have a background in engineering, specifically major project management, I am currently working in information security as a mid to senior executive (swapped careers due to a great opportunity a decade ago), and I recently graduated from a top MBA program (trying to be more marketable). I have three Master's degrees (Business, engineering, humanities), a number of graduate certificates in computer security, and went to one of the top universities in the US for my undergrad. And I have experience to match.
I don't know how to market any of this, however. In the US, the military experience/leadership carries a lot of weight, but I need someone who can translate it into a UK context. I can do quite a bit, I have a broad education, but I was hoping a headhunter could be the intermediary.
