I have to agree here, I have had three job interviews before that got ruined by the HR lady not knowing anything about IT.
They always end up asking "situations" ( competency interviews )questions, and trying to explain to them is like talking to a brick wall.
I have no idea why HR people even bother turning upto interviews.
Maybe they're seeing how you react to a customer that doesn't understand (or care) what the problem is - and how you deal with it?
We occasionally do that sort of role-play in interviews, have someone from HR ask the same question 3 different ways, I'll pretend to be frustrated myself and see how they react under the pressure. It can occasionally produce some strange results (and the occasional outburst too).
Just a few CV tips, drop the soundbites, especially the "more than 100% effort" because I always ask people who they're going to borrow effort from. Concentrate on conveying where you added value to the role, anything you achieved in measurable terms, if you lead a team, how many people was it, if you ran a datacentre what data/network outage stats did you achieve. SMART. etc.
