[QUOTE=Drsalvador;33937295]Occam's Razor, The question only specifies they break AT a certain height, not AFTER a certain hight.[/QUOTE]
Ah, of course.
[QUOTE=dgg;33937289]What? How does that test how far they can fall without breaking?
You're pulling it. Not making it hit something.[/QUOTE]
The question doesn't say anything about dropping the bulbs.

Just says they break after a certain height, like how your ears pop in an aeroplane.

It's very important to have an employee that actually reads and understands questions well, rather than thinking they understood it.
It's not a play on words. It's grammar.
If you re-read the question with this in mind you'll see that it actually doesn't make sense to assume that they are talking about light bulbs breaking because of fall damage.
[QUOTE=Zee!;33937383]Unless you're being asked by a lawfirm word play won't cut it.[/QUOTE]
If the question is misunderstood as a result of its structure is the fault of the questioner, not the questioned.

If the tank is filled with water, the water level cannot rise, since it would overflow out. Therefore it must fall.

Crafty way of asking for the [url=http://en.wikipedia.org/wiki/Binary_search_algorithm]binary search[/url] algorithm.
I'm confused.
For the anchor question, wouldn't the water level stay the same?
[QUOTE=garrynohome;33936222]Is this one a joke? How would anyone know that?[/QUOTE]
That's the one by Google, my response would be "I don't know but I bet Google does" or something like that which would sound good.
[QUOTE=pod;33938174]I'm confused.

I don't know whether it holds true in all cases, but I can see a scenario in which the water level would fall.
[QUOTE=pod;33938174]I'm confused.

When in the boat, the anchor displaces water through its weight, when in the water the anchor displaces water by its volume. Considering it's an anchor (probably metal) then it is denser than water it will displace more water through its weight.

But what about the air pressure from being in a tank?

Quite sure it's this too. Anchor in boat equals greater weight equals more water being displaced equals higher water level. If the anchor is thrown into the water, it's going to displace according to volume.

[quote]"Given 20 'destructible' light bulbs (which break at a certain height), and a building with 100 floors, how do you determine the height that the light bulbs break?" (Qualcomm)[/quote]
Take one lightbulb, try it on the first floor, unscrew it, try it again on the second and so on until it breaks. Nowhere does it state that you can't use one for several floors.
[QUOTE]"If you were a Microsoft Office program, which one would you be?"[/QUOTE]
Excel
Also in the question it doesn't say whether you need to do it as fast as possible, or do it with the least amount of lightbulbs broken, or both.

[QUOTE]You have a bouquet of flowers. All but two are roses, all but two are daisies, and all but two are tulips. How many flowers do you have?[/QUOTE]
f = number of flowers
f = (f-2) + (f-2) + (f-2)
(roses) (daisies) (tulips)
f = 3(f-2)
f = 3f-6
-2f = -6
f = 3
I have 3 flowers

That doesn't make any sense at all. The tank can have edges, preventing overflowing if the level rises.

No, the answer is that the man hole is round too :downs:
Not tech related but the supermarket I work at did briefly consider asking future applicants if they were any good at foosball, because we're such a fanatical bunch at it.

I notice how everyone is thinking about the anchor, I was thinking about if the boat was extreamly floatable, then the water level would rise if the anchor was put in water. The anchor might be small and have hydrolics so when it hits the bottom the chains assemble and extend therefore pushing the boat up and making the water level fall. There are many possibilitys depending on your imagination.
[QUOTE=BrainDamageStudios] The lightbulb question is solved easily.
You attach one of them to a car battery and step in the elevator, then go to the 100th floor, and take note at which floor the bulb breaks.[/quote]
EXACTLY what I was thinking, after all its easy and reliable.
I got stuck on the flower one because my brain stopped comuting and I couldent make sense of "all but two" I was reading way too fast each time so I personally think I would be better off if I heard it.
[QUOTE=DainBramageStudios;33940306]But then it won't be full?[/QUOTE]
It doesn't say anywhere that it's full. It's filled, not necessarily full.
Nor did they say that overflowing may not happen.
manhole covers are round to differentiate them from square storm drain covers so repair men don't accidentally go into the wrong one while not wearing their rubber poo-repellent suit
I actually feel kind of clever for getting the flower one intuitively, but now I need to figure out how the water displacement one works
This reminds me of a exercise book I was asked to use at a group job interview.
The exercise book had a list of objectives you must do.
It went something like this:
1.) Draw a circle in the top left.
2.) Draw a square inside the circle
3.) Draw a triangle in the top right
4.) Shout your name out
etc.
The trick to it was, the 10th instruction stated "only do the first 3 instructions".
So whilst I sat there having completed the 3 tasks. I waited, and every other person in the room shouted their name.
They didn't get the job as they clearly didn't read through the objective list before following the instructions.
I think this technique should be standard in jobs which failure to follow instructions, could lead to death/injury.

As a counterpoint to this, it should also be taught to safety managers, so that they know to put the important information first.
Stupid people do unsafe things, but if you don't take the stupidity of others into account you can be more unsafe than all of them put together.
