comment System Usability Scale and internal reliability
If you're talking about the thing at 2:30 all they're doing is looking for runs of the same number across several questions (somebody went down the test and marked everything "4" — or whatever. I'd personally be a little suspicious of that as a good metric since I've seen genuine folk do that…

comment System Usability Scale and internal reliability
I think you're mis-reading the intent. They're not pairs of questions that are asking the same thing in two different ways. It's alternating questions so that on one the "high" is agreement and on others the "high" is on disagreement with the idea that it would encourage the participant to read each Q in detail. This was good practice at the time SUS was created, but there's been more recent research that it can actually lead to more user errors. There's actually an 'all positive' version of SUS out there measuringu.com/positive-negative.php

comment Quick, Quantifiable UX Screener Questions
UX is a darn broad field. Can you talk about what the focus of role you're looking for? Research? IxD? Graphic Design? Usability Testing? IA? etc.

Go pick up a copy of Laura Klein's "UX for Lean Startups". I think it'll help.

comment How can I communicate the user, that the refresh button must be clicked to refresh the content?
Did you ask the test participants why they hesitated? I can think of several possible reasons (didn't recognise the icon's meaning, thought it refreshed the whole page and would lose their settings, etc.)?
