I've heard stories about insane interview questions and tactics from the likes of Google (impossible programming tasks) and Microsoft.
I flew to New Orleans this week and on the way up, I noticed how many baseball fields there are in the NY area from above. For example, I counted 28 baseball diamonds in Central park alone!
The next time I interview someone, I'm going to ask them "How many baseball diamonds are there in the United States?"
I've heard variations of this like "How many gas stations are there in the U.S." as well, but I like mine better.
I did a google search for this but didn't come up with anything.
