I would suggest that since this is a 'Thinking Test' it is not the answers that matter, but the way that the candidate approaches the problem that is important. Multiple choice is a way of dumbing down the assessment process. When using anything that makes the selection process more mechanical there is a danger of losing the genuinely intelligent 'off the wall' thinkers?
The problem is that then you need high level interviewers with the attended risk potential for bias in the selection process.
