Tricky Interview Question

[Varuna]

Just point to any spot on the table and say this is the exact position of the centre of this table.

Since the interviewer said that was the last question - he will not ask you to clarify your answer.

Which position in the centre? You need to pin point the location of the centre.

I think ZorrorroZ sounds right. Whatever jobs those questions were for are definitely not for me. Good fun though! Thks.

Yeah it is not so easy but good fun. Thanks for your effort though.

I will answer "b".

Because is the exact center in the word table.

What about another one?

Question: The interviewer asked the candidate "This is your last question of the interview. Please tell me the exact position of the center of this table."

Haha...good try but no prize. Thanks though.

how about this, heard its interview question for Facebook:

you have 25 horses, 5 lanes. With the minimum fuss / time spent, how do you determine which is the fastest horse?

One horse one lane... 5 timed races needed

 

[annexa]

2 horses per lane, facing opposite each other. 1 race can see which horse is fastest.

sorry...i went to check.

the precise version is here:

Twenty five racehorses, no stopwatch, five tracks. Figure out the top three fastest horses in the fewest number of races.

Let's divide the horses into 5 groups (A to E) of 5.
1. Race the five groups. Let's label the horses by the Group (A to F) and place (1 to 5).
The 4th and 5th in each group can automatically be elimated (since they are definitely not top 3).
That leaves you with 15 horses (A1-3, B1-3 etc).
2. Race the winners of the five groups (A1, B1, C1, D1 and E1). Again, bottom 2 (Let's say D and E) can be eliminated. Also, their entire group can be eliminated since none of them can be top 3). The 2nd and 3rd of the group coming in 3rd (let's say C) can also be eliminated. B3 can also be eliminated since it is definitely slower than A1, B1 and B2. You are therefore left with 6 horses (A1-3, B1-2 and C1).
3. A1 is definitely the fastest horse of the 25. So just race A2, A3, B2, and C1 and take the top 2.

Total = 7 races.

I was thinking along the same lines but decided not to as in the shortest time means not having so many races. Those horses will be too exhausted lol. Kudos to you for the logical answer.
