Google has an ad on the inside cover of MENSA magazine this month. This is an interesting move because while they may be targeting people with good problem solving skills, they are also targeting an older demographic. I'm not sure there are many young MENSA members. There is a note at the bottom saying that anyone who can solve the problem will get their resume moved to the front of the line. The problem is a parking garage with six poles. Five of the poles have a number, and you have to figure out what should be on the sixth. I'll put the numbers below as they would show up if you were looking down from the ceiling of the garage.
I haven't solved it yet, but I hope to work on it later. If anyone thinks they know the answer, leave it in the comments or send me an email. I don't know if it makes a difference, but there is an EXIT sign in the picture on the front row (the 26 ? row) pointing to the right.
UPDATE: The comments have a link to a picture of the problem…
