Technical interview questions often consist of brainteasers, riddles and such, designed to measure your analytic and problem-solving skills. Common technical interview questions are along the lines of "How would you improve .........?" and "Why are manhole covers round?" etc

Simply put, manhole covers are round to prevent them from accidentally falling through the holes. (Square and rectangular covers could fall through diagonally.) To further impress the technical interviewer, you might add that round covers are easier to move away from the holes, because they roll. You might also add that a cylinder is the strongest shape against the compression of the earth, so a manhole cover is round to fit the cylinder beneath it.

BUT
