Google's toughest interview questions revealed

Google applicants must prepare themselves to answer some tricky questions when they land themselves an interview at the company.

With about 2 million people applying for a job each year, it is almost 10 times harder to get a job at Google than it is to get into Harvard. Those lucky enough to land themselves an interview should get ready to answer some tough questions.

Those that make the cut will be asked questions like: "How many haircuts do you think happen in America every year?"

Business Insider has compiled a list of some tough and at times plain odd questions asked by recruiters at Google. The list was compiled using Glassdoor’s information about the tech giant.
