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).

I had one question for each interview and both were probability puzzles. Here is the tougher one: you have a bag of N strings, and at random, you pull out a end. You pull out another end and you tie the two ends together. You take another two string ends and tie them together. You repeat this until there are no loose ends left to pull out of the bag. What is the expected number of loops?
