Extreme interviewing techniques seem to be the order of the day among employers and some candidates are faced with questions such as, 'If you were a dinosaur, what would you be?'
Although they say the way a candidate handles the question is more important than the actual answer, chances are that if someone answered Tyrannosaurus rex, they won't be getting the job.
The candidate would be told, 'Aha, so you are a cannibalistic predator preying on the weak, are you?'
The technique originated in California's Silicon Valley.
Google, which is based there, is renowned for its intense interview process, with 50-page dossiers sometimes being prepared for a potential employee.
One question a recent candidate was asked was, "You are stranded on a desert island. You have 60 seconds to choose people of ten professions to come with you. Who do you choose? Go!"
Computer manufacturer Hewlett-Packard prefers questions such as, "If Germans were the tallest people in the world, how would you prove it?" - a reference to the first line of their national anthem, Deutschland Deutschland uber alles.
The idea of extreme interviewing is to see how quickly job seekers think on their feet and one of its pioneers was the late Steve Jobs, co-founder of Apple, who put interviewees through their paces.
Dealing with a candidate he considered dull, Jobs launched into a chicken impression, flapping his arms and clucking to judge his reaction.
David Moyle, a headhunter with the Eximius Group in London, admits he has used the dinosaur question to recruit.
"We are trying to give candidates an opportunity to show their personality, rather than just showing how they perform in an interview," he said.
