Sometimes the hiring practices of even the biggest and most successful companies can be outright ridiculous.

There can be bizarre interview questions that seemingly have no answers. There can be standards -- like not hiring anyone who attended a college outside of the Ivy League -- that will knock candidates out of the race before they even approach the starting line.

Google used to be the shining example of these practices. It had high standards and asked silly questions.

The questions were so nuts that they were eventually banned from being asked. That's right, banned.

In 2009, Seattle job coach Lewis Lin put together a list of 140 questions his clients were asked by Google. We've picked out some of the wildest and added a link to the whole list at the end.

Future Google employees should be grateful these questions are no longer on the table.
