133,124 data interview questions shared by candidates

0) Tell about your current job and work experience. I) Conditional probability dice questions: a) Expected pay-off of a single roll single dice game (Entry fee $3). The amount the player gets is the face value of the dice. Ans: $3.5 - $3 = $0.5 b) Expected pay-off of a double roll single dice game(entry fee $4). Rule: the player can either hold or continue the game after the first roll. If the player continues the player forfeits the money received after the first round.Ans. $4.25(Expected values check stack overflow for the math) - $4 = $0.25 c) Which of a) or b) has a higher payoff. Ans. obviously game (a). 2) The probability of watching at least one star in 1 hr = 0.64. What is the probability of watching at one start in 30 mins? Ans. 0.4 (Again search StackOverflow) 3) What kind of casino machine would you recommend based on two options knowing that patrons play option B longer but the casino earns slightly less per hour from the machine than option A?

Without going into detail, they wanted both Python code for transforming raw data into data in some form from which one could make predictions, as well as a written description of what was done, why, and the modeling approach one would take.

(The only numerical question requiring Excel/Calculator) Finally, gave me a probability based, expected default rate question. The exact question was that the company has to calculate the expected default rate given the minimum return they look for is 15% over lease value. The given lease value was $1000, and the scaling factor (lease cost) was 60% of lease value. Another cost, the cost of service that the company bears is $50, which is taken from customer while making the deal. Now, to simplify there were only 2 possible outcomes mentioned which is full payment over 12 months or default before the payments start.
