Light Test...

(Ooooh me sir, me sir I just figured it...but I won't tell)

What silly (ba)nana of an electrician installed that?

• Does leaving the door open and looking in from outside count?
• Does knocking the wall and door down so that the switches are in the same room count?

wow good thinking, i would have just drilled a hole in the wall

Very good thinking! That is the correct answer!

A friend of mine is a facilities guy. When he was hired, they used this question as part of the interview. He shared it with me, and I immediately thought CR 4 would enjoy it.

Ah, but that's only true if you know the switches are wired with up is off or are labelled off/on . (Which the question doesn't specify)

Switches are labled: "UP YOURS."

Do the switches down under work up = open and down = closed; and if so, why are you following this upside-down convention? Oops, I need to ask some Ozzies and Boers instead. Of course, I recognize that this is all about making the toilet bowl vortices rotate in the correct direction to satisfy Coriolis, whoever that was, but I am willing to descend into abject confusion over momentous questions like this. After all, does your refrigerator light really go off when you shut the door, does a falling tree make a sound if no one is there to hear it, and does a bear...? Inquiring minds want to know about these deep philosophical questions.... Aristotle would be proud/ashamed...

And it was there in the CR4 challenges a couple of months back, only it was in a shopping stores.

No body remembered .

On the other hand, walking into the room three times would take about 30 seconds, << 10 minutes. The question's answer is admittedly ingenious, and deserves credit. However, failure to "get it" is not much of a discredit, so I doubt its value in an interview. (Not that as an interviewee I would mind, because I knew this. Similar techniques are also useful for checking fan function and direction, for instance.)

You don't visit the Challenge Questions, do you ? Bwahhh. What kind of lights, are they candles (yeah, the switch operated kind )
