actuarial interview questions shared by candidates
you have a 9x9x9 sided cube made up of 1 squaree inch squares. If all sides are painted how many cubes have no paint on any side?
Zero... because all sides are painted; either you re-wrote this wrong or you trying to walk her through mathematical equations to answer this obviously simple question is the reason you didn't get an offer.
Eric, calm yourself. Im guessing he means that all sides (like he said) are painted. i.e. only the cubes on the outside of the cube. So the way to solve would be think of an 8x8x8 cube inside of a 9x9x9 cube, where are all of the 8x8x8 cube pieces have no paint on them. I think the answer is 8 cubed or 512 then, but dont quote me on that.
I agree with John's answer, but the wording is terrible. You have to assume that the cube is built from 9^3 one inch cubes. Then the problem becomes simple to visualize and solve. I hope the interview explained the problem clearer than this poster.
A train left station A going 20 mph, and at the same time a train left station B going 15 mph. A bird sat on top of train A and started flying at 40 mph as soon as train A left. The bird flew to train B, then back to train A, then back to train B, and so on, until the two trains met. The track is 70 miles long. How many miles did the bird fly?
One specific interviewer has this question and tends to use it a lot so I'm told: You own 2 restaurants. The cumulative amount of customers in the first 3 weeks are as follows: Restaurant A: 100, 200, 1500 Restaurant B: 250, 750, 1500 You are about to open a 3rd restaurant . Predict what amount of customers the first week will hold. Explain how you came up with that answer. explain any assumptions you use in your analysis
