‘How do you weigh an elephant without a weight machine?’
We have all been through some pretty weird interview questions at some point in our lives, but questions asked by tech giants to potential candidates had literally left them scratching their heads.
Have a go at this: given the numbers 1 to 1,000, what is the minimum number of guesses needed to find a specific number if you are given the hint “higher” or “lower” for each guess you make? If you are able to answer that question, you may have a fighting chance to become a software engineer at Facebook.
Glassdoor.com, a job community website, has published 25 of the most oddest interview questions of 2010, based on more than 80,000 questions shared by candidates on its web site. I wonder how many of them got hired.
Anyway, here are some questions asked by tech companies like Apple, Google, Amazon, etc (thanks PCMag!).

“There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?” – asked at Apple, Software QA Engineer position

A train leaves San Antonio for Huston at 60mph. Another train leaves Huston for San Antonio at 80mph. Huston and San Antonio are 300 miles apart. If a bird leaves San Antonio at 100mph, and turns around and flies back once it reaches the Huston train, and continues to fly between the two, how far will it have flown when they collide.” - asked at USAA, Software Engineer position
