The 20 toughest job interview questions in the world

Candidates are facing tougher and weirder questions than ever in job interviews

Impossible to prepare for; unrelated to the job: jobseekers are facing tougher and weirder questions than ever in job interviews.

Employers are turning to tricky questions to quickly sort through high numbers of candidates, so that only the very best shine through, according to Joe Wiggins, spokesman for Glassdoor in the UK.

"Often it is to see how you react under pressure," Wiggins said. "It’s to see what happens when the rug is pulled from under you – how do you prepare for the completely unexpected?"

Consultancies and tech companies tend to use these kinds of questions more than other sectors, Wiggins said, while interns and entry level candidates get asked more brainteasers, or 'oddball', questions than those higher up.

"The number of candidates for interns is so high that the idea is to throw a grenade in and see what happens," Wiggins told the Independent.

Glassdoor, a site where people anonymously review companies and employers, sifted through user contributions to work out the toughest interview questions in the US and the UK. They ranged from the kind of questions that sounds like they should be debated on a Friday night down the pub, to mathematical conundrums that could be on exam papers.

Candidates at ASDA say they have been asked which superhero they would be, while one candidate at Jefferies, the investment bank, said they were asked their opinion on the ‘Blair Witch Project’.

Google, famous for its weird and wonderful interview questions, once asked interviewees to calculate how many calories are in a grocery store. Some tried to figure out a mathematical formula to work out the answer. Others said none – because the calories are in the food.

HR professionals find that the ‘back to school, back to work’ mentality that sets in in September can make it a busy time for interviews. “The message for candidates is to be prepared for anything and try to practice these sorts of questions, but not to worry too much,” said Wiggins. “No one is going to know the answer to these things.”
