Ok now assume that the day is split into surge and non-surge demand hours. Non-surge demand lasts 4 hours and has 800 rides. Surge demand lasts another 4 hours and has 1,600 rides. Assume you can only hire drivers for the full day. How much would you need to charge during surge hours to breakeven on your profit from the first question?
The company manufactures 3D Printers. Who should they target selling it to and which one will be more profitable? End customers directly or through retailers? Interviewer asked me to plot graph to show the volume of sales with respect to time for each scenario. Asked to calculate the profit in 2years giving fixed cost 6.6m, over head costs 2.4m/yearly, cost of the item=$250 price of the item sold=$500 and no of units= 2000/monthly. Altered the numbers: when 25% of printers breakdown and cost of repairing each one is 200$. What are the additional printers to be sold to make the profit in 1 year?
CASE: Recovering Written-off Past Due Balances 6 months past due, avg $2000 balance, 15% pay in full, profitable? If introduce settlement option for 60% of balance, 10% pay settlement but 5% of them dont pay in full, better choice? With new model, now 9% pay in full, but with settlement option now 10% take settlement but a third of original payers dont pay in full, better? etc. (poorly worded and confusing case. unhelpful vague interviewer, arggg, cost me the job).

It was regarding configuration management of code as I had worked on VSS and the questions were on TFS.
1) I have class hierarchy and should create array of different instances of this hierarchy. They asked me to write a function which iterates this array and executes different methods according to the instance class. I suggested that downcasting is a bad idea and that it can violate Liskov substitution rule of the SOLID principles, and this problem should be solved using collections and generics, but they did not accept this answer 2) Create Queue N size using only N size array. 3) some Java concurrency related questions: synchronized volatile, atomic, etc....
