Interesting idea for an interview question. To test an applicant's ability with abstract. Ask them how tall a piece of paper would be after folding it 42 times.
"Recruitment and Employment Confederation/KPMG monthly permanent placements index fell to 46.3 last month, down from 46.8 in January with employers more likely to use temporary workers to fill roles...(but) Billings for temporary workers rose but at a softer rate than in January"
There are 3 levels when asking a question. First, response is usually superficial, second gets deeper understanding and the 3rd shows a candidate's true colors. How to get to the third level is the hard part.
