Saville Assessment Software Developer interview questions

Aptitude Assessment required before getting to the interview process, if you don't get 70% or more then you've got no chance at an interview (according to the recruitment agent). I understand that because the company develop this software they expect people to pass these aptitude tests. However I think using this approach is flawed. If you're used to doing puzzles and aptitude tests, possibly someone who may have just left formal education then you'll probably have a better chance at passing. You may get someone who scores highly but has no business experience or has the personality of a wet rag. Perhaps a face to face interview first would be appropriate and then an aptitude test if they want to take it further. They do offer you the opportunity to prepare and if you're scoring 100% on the preps then you have good chance of passing, however the actual testing environment can be daunting.
