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

51 Answers

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

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. 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

Uber

From the in-person panel interviews: - Uber is opening up a city remotely (i.e. Milwaukee will be operated out of Chicago). How would you make the drivers in Milwaukee feel equal to the drivers in Chicago. This was maybe the worst, most vague question of them all. - Uber drops you in a new market (i.e. Oklahoma City) and says you have two weeks until we open here - go! What do you do? - Say an Uber black car driver makes $30/ride with a 20% commission. How do you convince him to upgrade to a new made up service UberSuper with a 25% commission? What costs will the driver incur in upgrading. How much more will he have to make each week, etc. Note: it's not enough to just walk them through mentally how you'd do this, be prepared to do the math on the fly. Very annoying. - An Uber competitor opens in your city with unlimited cash capital, if you were them how would you steal Uber's customers? If you were Uber how would you convince drivers not to leave?

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

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

12 Answers

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

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

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 & they went above & beyond? Whether it's an inter-office request or anything else, you are always either someone's customer or vendor & this is called "giving excellent customer service". This question is begging for Excellent Customer Service. Less

CASE: Cross-selling Credit Insurance to Cardholders direct mail: .50, 1% response rate, avg balance $1000, 5% claim insurance, etc. Profitable? How make more profitable? What if response rate doubled but claims doubled? Make chart of profit curve, what does it mean if..., etc.

12 Answers

@ ghachla: The response rate is 1% that is 1 out of 100. I assumed 100 people are sent the mail. Hence the response rate is 1. As for the claim rate, the people who don't respond can't make claims. So out of the people who respond, the claim rate is 5% (i.e 1 person responds in 100 and out of that 1, 0.05 make the claim); Or to make it more clearer, if we assume 10000 people are sent the mail, 100 respond (because of the 1% response rate) and 5 out of the 100 make claims (because of the 5% claim rate). Less

Thanks for your response and guidance. I knew the revenue is monthly, but i thought claim rate is also monthly and hence calculated profit for each credit insurance sold per month. In light of your clarification Profit per card insurance per year = (10*12)-50-50 = 20$ per year If we chose to calculate per month, we will need to consider monthly claim rate as (5/12) and also amortize the marketing expense over next 12 month. Profit per card insurance per month = 10-(50/12)-(50/12)= (20/12)$ per month The profitability equation (per card per year) = 120x-10xy-50 For calculating any of the break even rates (x or y assuming 1 is known), 120x-10xy-50 = 0. For graph, P = 120x-10xy-50 Let me know if my analysis/answer is accurate and up to the mark. Thanks a lot for all your guidance. Less

Looks like I left out the price of the insurance: customers would pay 1% of monthly balance for insurance. Less
