### 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

inane interview questions

The kardashians

Answering stupid questions from moronic interviewers.

### 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 confirm it is the same test... it is really hard..., thanks god I prepared before with.. try www.uber-analytical-test Less

Anyone have any ideas on how uber makes drivers in Chicago and Milwaukee feel equal? 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.

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

@ 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

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

### You have the choice between using first class or third class mail for a letter you are sending out to potential customers. First class costs \$0.50 per piece and reach 100% of potential customers. Third class costs \$0.40 per piece and reaches 80% of potential customers. Which do you use?

either one is good. For example, you will reach 0.8 person by spending \$0.4. If divided 0.4 by 0.8, we get that we will reach 1 person by spending \$0.5. So two methods have the same effect. Less

First class should be used, as the cost of each delivered letter will be the same, but you will reach all of your intended audience. Example: 1000 pieces to be sent, sending first class costs \$500 and reaches 1000 (\$.50 per peice), and sending second class costs \$400 and reaches 800 (\$.50 per piece) Less

@gaurav: don't make it too complicated. they just want to know the costs of reaching the customers. peppermint is right. Less

### Presentation on what my plans would be within the first 90 days

Sean did not write this review. I did and I am a genuine person who had an interview with Sean. Please do not have a go or accuse Sean of writing this review. I wrote it and it was my typo. This review is a true reflection of my experience which is the reason I felt compelled to write it as my experience with the owner was professional. Less

Another fake review. If the company was so good why did you not take the role? Hmmm Less

Because there was too much travel to the Pand office which I could not commit to. Leave it at that. You have obviously a grievance with this employer which is between you and them. That doesn’t mean my experience would be the same. I fact it wasn’t. Not a fake review. Get over it and yourself- move and jog on pls Less

### What is the fastest amount of time you can get 4 people across a bridge. Each person takes a different amount of time .. 1 minute, 2, 5, and 10. They can cross 2 at a time but need a flashlight to cross.

It's 17 minutes. The actions are of the form (x, y, -&gt;) or (x, ), (1, ), (2,). Sum up the maximum of each tuple and get 17! Less

17. 1 and 2 go together for 2 min. 1 runs back for 3 min. 5 and 10 run across for 13 min, 2 runs back for 15 min and 1 and 2 run across for 17 min. Less

No, its 17!
