Victor,
The happy chappy I believe you refer to was called Xander, a Dutch gentleman who'd driven over from Holland the day before in order to take part in Stage 1; he then left to drive home straight afterwards! You may take some solace from knowing he didn't find the Spatial Reasoning or Diagramming so easy!
I was sat immediately to Xander's right; about 5 rows from the front, 2nd column in from the left, next to the poster about Lateral Separation if it helps! Frankly, I thought I'd failed having not finished the Maths paper, but was quick to realise when we were taken to the other room that it must've been ok (how often do they put you in a more comfortable room with pencils and rubbers to tell you you suck?)
Not in contact with any of the others from our session, so havne't heard anything of them. All I know is my progress, which is about as quick as you'd expect...
To Darn & Phil;
I'm negligent to pass on any information that I know of about the personality test; the whole point is that you're honest and truthful about the questions, else the responses become about a fictitious personality, rather than the test takers!
