25 horses, 5 race tracks. How many races you have to run to select top 5 horses.

The answer is 9. Assuming: - There's no time measuring (stopwatch), just relative places. - The horses perform consistently. - A maximum of 5 horses per race. First we need 5 races (A to E) to get relative scores for all 25 horses. Let's take a worst scenario: the list was already ordered (A1 fastest and E5 slowest), so race A contained the top 5. The 6th race would be the winners of the 5 races (A1, B1, C1, D1, E1), and would give A1 as the fastest of all. This would also mean that some horses can be excluded (only 4 more places to fill): B5 C4, C5 D3, D4, D5 E2, E3, E4, E5 For the 7th race, A2 would replace A1, and A2 would be appointed as the runner-up (of all). We also can exclude some more (only 3 more places to fill): B4 C3 D2 E1 For the 8th race, A3 would replace A2, but as E1 has been excluded, we got a vacancy. Let's add C2 for worst case scenario. The winner would be A3, and we can exclude more horses (only 2 more places to fill): B3 C2 D1 At this point there're only 5 horses who have not yet been classified or excluded, so the winner and runner-up of the 9th race would give 4th and 5th overall.

You guys are not doing CS! 10 runs is my answer. 1. randomize 5 groups, each of 5 horses 2. rank them within each group, I will use Anuradha's notation (5 races) 3. pick the best of each group, race to figure the 1st place, call it A1 (1 race) It should be clear, it wins all times, every one lost once. 4. remove it. substitute 2nd best in. repeat 3 (in my eg. A2,B1,C1,D1,E1) now you have second place. keep going, you get the first 5 and ranking! So, 5+5=10 races in total. Less

Anuradha's solution still has problems. (Even if we go with Anuradha's assumptions that you can only race one horse per track, and also assuming that we don't have a stopwatch and must compare horses placing positions) What if the fastest five horses are A1, B1, C1, D1, and E1 ? In Anuradha's second step, he elminates two of the fastest horses (D1 and E1) . He's assuming that A2, B2, or some of the other horses from the other heats are faster, but he hasn't actually tested to see if that is true. Less

Why do u want to work for JetBlue

June 30

Why are they taking so long? Have you contact them? Did you do your background and drug test Less

April interviewee, how long after your interview, did they contact you regarding bkgrd n fp? Less

1)Tell me what you know about JetBlue? 2) what do you like or dislike about your current employer? 3)tell me a time you went out of the box for a customer? 4) tell me a time an employee didn't do their job and what did you do?

I also interviewed at the LIC headquarters on October 5th 2015 and got an email that ask for DOB and SS# and there was an email stating that there was an issue with the link that was given and that we should wait for the next day which would've been Oct 9th. Then just yesterday Oct 21st I got the email stating they got my info and that they appreciated my patience in this matter.. So I'm sure it's just a matter of time for the background check to happen Less

Hey I got selected. I also did interview on the 18 of June. I just finished my background now I'm just waiting for drug test which I will pass flying colors Less

I just got the e mail that tey received my information. I guess the next step is background check. Less

If I handed you a rubiks cube and told you that it had to be solved by tomorrow, how would you respond?

Such questions are really stupid IMHO and I feel like punching the interviewer for asking crap like this. I don't think such questions prove anything. A person can be really good at handling situations but not respond likewise and a pretentious person can do very well in such cases but do a horrible job when hired. Please interviewers stop with such questions! Less

If I were asked this question I would say, "You'll have it today". How you do it isn't too important, there are literally a million ways to "solve" the rubiks cube they're handing you, it's not a cube, it's any problem they need solved, just get it done as soon as you can, wouldn't you like it if you asked someone to do something &amp; they went above &amp; beyond? Whether it's an inter-office request or anything else, you are always either someone's customer or vendor &amp; this is called "giving excellent customer service". This question is begging for Excellent Customer Service. Less

Anyone that asks a question of this nature is looking for a typical, corporate behind kissing answer. personally I was much more impressed with your honest answer than I would be by someone, whose nature and work ability I have no idea about, answering like someone else did on this with "You'll have it today." You could have answered with that and have not the first clue about "customer service", because it is just a brown nosing answer. To me, a good answer is honest and forthright, and I never want to just hear what the interviewee thinks I want to hear. Less

Rate yourself on a scale of 1 to 10 how weird you are.

One number lower than whoever came up with this question

I am within two standard deviations from the norm...

If in a room there are 10 persons and if each person has to shake hands with all other then total how many hand shakes will be there

10C2=45

10(10-1)/2

simply formulas: n*(n-1)/2 (n-1)*(n/2)

Behavioral based questions were easy to prepare for. Amazon prefers the STAR (situation, task, action, result) method to answer. Would suggestion preparing for the math flow question. I was asked the following: You have 30 associates who all work an 8 hour day, 5 days a week. 2 need to be in indirect (non-volume producing) roles. Your direct (production) rate is 150 units per hour, but you have two 15-minute breaks during the day. How many units can your department produce in a 40 hour week?

(30 - 2) associates = 28 28 associates/hour * (8 - 0.5) hours/day * 5 days/week * 150 units = 157,500 units/week However, this assumes 100% utilization all the time and this is probably unrealistic. I would then apply a reduction to efficiency to account for unexpected delays. 157,500 units/week * 90% = 141,750 units/week ... final answer. Less

The correct answer is 157500

This is a math question not an estimation on potential variables through sickness, breakdowns etc The answer is 157500 Less

There are 27 balls with one ball having additional weight. Total how many attempts you have to make to check all balls using a sisaw

3. group the 27 balls into3 groups of nine, weigh 2 of the groups. If one is heavier, continue with that group. If they are equal, continue with the unweighed group. Break those nine into 3 groups of 3, weigh 2 groups. If one is heavier, continue with that group, otherwise use the unweighed group. With the 3 left, weigh any two. If one is heavier, you have it. If they are the same, then it is the unweighed ball that is heaviest. You have used the scale 3 times Less

3 You can guarantee the answer in 3 steps, if required. However, you no longer stand a chance of obtaining the answer in the first 2 weighings as I described immediately above. 1. Divide balls into 3 groups of 9. --&gt; Weigh two of the groups. This will identify the heavy group. 2. Divide the identified heavy group into 3 groups of 3. --&gt; Weigh two of the groups. This will identify the heavy group. 3. Separate the 3 balls in the heavy group and weigh. --&gt; This comparison will identify the one heavy ball from the original group of 27. Less

3 attempts - attempt 1 - divide 3 sections 9balls 9balls 9balls pick a section which is different in weight, attempt 2 - divide 3 sections 3balls 3balls 3 balls pick a section which is different in weight, Attempt-3- divide 3 sections 1ball 1ball 1ball pick a ball which is in different in weight Attempt 3 - Less

Pretend 1% of the population has a disease. You have a test that determines if you have that disease, but it's only 80% accurate and 20% of the time you get a false positive, how likely is it you have the disease.

You don't need the test. The answer is given... 1% of the population has the disease... Answer: 1% Less

1%. The first sentence gives you all the info you need.

1% chance if using global population. Chances would decrease or increase depending on certain variable or demographic factors so I would say you need more data to give a specific answer. Things like age , gender , race , need to be taken into consideration if you are a 33 year old male and the subject disease is ovarial cancer then you have 0 percent chance . If you are a 40 year old nun and the disease is The clap you have less probably of being infected than say a 26 year old prostitute .. Less
