Can You Answer These Tricky Job Interview Questions From Apple Inc by MissTechy(f): 7:53pm On Apr 12, 2015
If you are an active reader on MissTechy .com you'd remember when I asked if you had what it took to work at Google, In my opinion, if you can work at Google, you can work anywhere – here’s something similar to that.

I saw this Interview Questions on Glassdoor and I just felt it might be very useful to some of us given that most companies especially in Nigeria like copying these big tech guys. We all know that Apple is one of the biggest Tech companies in the World and to get a job there wouldn’t be so easy.

Glassdoor decided to make this easy by providing some questions Apple Inc uses to select their employees – I would be revealing 3 questions here that I feel are more brain tasking and require more brain knowledge. Is your brain equipped to answer these Apple’s Job Interview Questions? If Yes? Let’s do this smiley

1. How many children are born every day?


2. If you have 2 eggs, and you want to figure out what’s the highest floor from which you can drop the egg without breaking it, how would you do it? What’s the optimal solution?


3.You have 100 coins laying flat on a table, each with a head side and a tail side. 10 of them are heads up, 90 are tails up. You can’t feel, see or in any other way find out which side is up. Split the coins into two piles such that there are the same number of heads in each pile.”

4. There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?

So who can answer any?

1.Count 50 coins and place one side, count another 50 and place another side.
2. Say for example d apple box is labelled orange, the orange is labelled orange and apple, and the orange and apple is labbeled apple.
Say now I open the box labelled orange and I find an apple. Ill then know that the box labbeled apple must contain another fruit ( assumingly orange). Don't know d rest.
3. At least one child.
4. Go to d 22nd floor and drop the first egg, d result will teach u whether or not to throw d second egg.

For question 1, there's is no way they'll expect me to know that...my answer will be sarcastic. No baby is born everyday. A baby is born once.




For question 2, [Modified] optimally, I will go to floor 1, drop one egg, then go to floor 3, drop another. If it breaks, go to floor 2 and confirm it is 3 not 2. if it doesnt break, i wont waste time on 2, ill move to floor 5. if it breaks, 4 to confirm, doesnt break, move to floor 7. and so on and so on.

For question 3...still thinking


For question 4,

since boxes are incorrectly labeled, I will take chances. If I put my hand and bring out an Apple in box 1, the label will say either oranges or both If it is all apples. If it contains both, the label will be oranges or apples. With this, I know what the contents of box 1 is.
I then swap the label for box two and three

THE EGG QUESTION

Let x be the answer we want, the number of drops required.

So if the first egg breaks maximum we can have x-1 drops and so we must always put the first egg from height x. So we have determined that for a given x we must drop the first ball from x height. And now if the first drop of the first egg doesn’t breaks we can have x-2 drops for the second egg if the first egg breaks in the second drop.

Taking an example, lets say 16 is my answer. That I need 16 drops to find out the answer. Lets see whether we can find out the height in 16 drops. First we drop from height 16,and if it breaks we try all floors from 1 to 15.If the egg don’t break then we have left 15 drops, so we will drop it from 16+15+1 =32nd floor. The reason being if it breaks at 32nd floor we can try all the floors from 17 to 31 in 14 drops (total of 16 drops). Now if it did not break then we have left 13 drops. and we can figure out whether we can find out whether we can figure out the floor in 16 drops.

Lets take the case with 16 as the answer

1 + 15 16 if breaks at 16 checks from 1 to 15 in 15 drops
1 + 14 31 if breaks at 31 checks from 17 to 30 in 14 drops
1 + 13 45 .....
1 + 12 58
1 + 11 70
1 + 10 81
1 + 9 91
1 + 8 100 We can easily do in the end as we have enough drops to accomplish the task


Now finding out the optimal one we can see that we could have done it in either 15 or 14 drops only but how can we find the optimal one. From the above table we can see that the optimal one will be needing 0 linear trials in the last step.

So we could write it as

(1+p) + (1+(p-1))+ (1+(p-2)) + .........+ (1+0) >= 100.

Let 1+p=q which is the answer we are looking for

q (q+1)/2 >=100

Solving for 100 you get q=14.
So the answer is: 14
Drop first orb from floors 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, 100... (i.e. move up 14 then 13, then 12 floors, etc) until it breaks (or doesn't at 100)

1. More than 1.
2. Start with the ground floor, if the egg breaks, then that's the minimum floor the egg can drop.
3. Split the coins into half, 50 here and 50 there. Since they all have heads, then there are equal number of heads on both side.
4. When you take out the fruit, relabel that box to the correct name and simply switch the other two name on the other boxes. And if u happen to pick a fruit from the box with the two fruits, just relabel with the name of the fruit u picked and switch the name on the other boxes.

1; as much babies as to fill up for people who die everyday
2. That is a no answer question because u cannot drop an egg from any angle without it breaking

3; since I can't feel nor see the coins the probability of having equal heads is 0

4; for this one I will need ojoro, take style look into the opened box or use hand feel the fruits to see if it contains apple and oranges then I can correctly guess the remaining two boxes

1 Due to constant increase in world population, number of children born daily is more than number of people who die daily.

2 Drop the egg from the minimum floor/ height and go higher until it breaks, the floor you last dropped it before it broke is the highest from which it can be dropped without breaking, assuming the eggs are identical and repeated impact doesnt weaken the egg.

3 We are not told to have the coins heads up or tails up after divinding, just to have equal number of heads, therefore you just split into 2 piles of 50 each. All the coins have heads and tails.

4 Since all 3 boxes are wrongly labelled, you know the one carrying label for orange and apple contains one fruit only, and one of the other two with label for one fruit has the mixture, pick a fruit from the box labelled orange and apple, and identify the fruit, then change its label to the right one, now replace the label taken from the second box to replace the orange and apple label on the firs box with that on the third box and put the orange and apple label on the third box.

For the egg question:
Since we are to use the most optimal method, Start with the two eggs in your hand and proceed to drop one from the lowest possible floor if it doesn't break then proceed to the next floor without picking up the first one and have a try. Go pick up both at once to conserve energy (resource) and proceed to higher floors in that manner. When one finally breaks you note the last floor before that floor for your answer.

For the children question:
I say children gets born once.

For the apple and orange question:
The key to the answer is the fact that all the boxes have been labelled incorrectly. I will dip my hands in a box as requested, identify its content correctly. Now that single step involves labelling one box correctly and removing a wrong label from another. I will then proceed to swap the label I removed from the box I dipped my hands in and swap it with the third box since I know the label of this third box is incorrect from the onset(a fact revealed in the question) and the only incorrect label left is the second box. This is fact because we know the two boxes with unconfirmed labels has one wrongly labelled. Is only a matter of swapping them after identifying the first boxes content.

As for the coins question:
That's the most simple of them all. Simply split the coin into two equal parts. The question says we should split them into two stacks with equal no of heads and not equal no of heads up or heads down.
