I recently finished up a complete interview process with DraftKings for the Data Analyst position. I submitted an application through their website and was contacted back about ~1 week later looking to continue on with a phone interview. The first phone interview was about ~30 minutes in length. I spoke to a current manager on the analytics team for about half of the time about his current responsibilities and my resume, and then we moved onto the case question which I've outlined before. Finally, we had a few minutes to catch up about any possible questions that I had. Overall, I knew that I butchered the final part of the case question, and did not expect to here back because of this. However, about 3 weeks later, I was emailed looking to follow-up for a second phone interview. This one followed a the same structure (resume review, case, questions) but was a bit longer and again was with a manager of the analytics team. I am lead to believe that these second phone interviews are infrequent - that you either do good enough on the first to proceed or are cut. This time I managed to crush the case part and was invited the next day for an in-person the next week. I was flown out and put up at a nice hotel in Boston. The interview process lasted just over 4 hours. I dealt with, in order: - 2 separate case interviews with different managers and an hour allotted to each - a 1 hour lunch break with two members of the analytics team. Didn't seem to be any pressure here, though the team members had a lot of interesting things to say and were good about answering questions - a 1 hour behavioral interview, mostly resume review and speaking to work experiences, again with a manager of the analytics team - a ~30 minute review with the HR lady When I spoke with the HR lady, I was informed that typically they'll send you home early if you did not perform well enough, and that reaching her meant that you were likely good enough. Alas, this was ultimately not the case for me, despite the glowing reviews she gave me. I was contacted by phone the next day and told that while I was a great cultural fit, I came up a bit short on one of the cases, which kinda contradicts what she had to say the day before, but oh well. Everyone was super hospitable, friendly, and informative.

Questions d'entretien [4]

Question 1

Phone Interview #2 A)You are presented with a game: you roll a die and are paid based on how many pips are rolled face up (1 pip = $1). If you do not like your first roll, you may elect to re-roll, but only once. As a rational human being, what is the most you'd pay to play this game? B)How does this change if you have to pay $1 for the re-roll?

Question 2

Phone Interview #2 You are playing a game of baseball. There are two outs in the bottom of the ninth, and you are down by one run. You are currently a baserunner on first base. [Obviously, you must score or else the game ends]. A)You are trying to figure out if you should steal second base or not. What kind of information do you need to know to inform this decision? B) Every batter in your lineup has identical odds.They get a single 50% of the time and they strike out 50% of the time. If you are on first base, you cannot score on a single. If you are on second, you are guaranteed to score on a single. You successfully steal 75% of the time. Should you steal? [I may be missing some of the nonsense here, but this is all the relevant information] C) It turns out the pitcher acts a bit differently with a runner on second [regardless of who the batter is] and no other runners on base. Under these circumstances, he is 50% to strike them out, 40% to surrender a walk, and 10% to surrender a hit. How does this change things/ should you steal?

Question 3

Case Interview #1 The first case is about running an amusement park. You outsource the running of the park to a company you pay a flat fee (so just ignore that going forward). You erect a new rollercoaster and notice that your total revenue has now gone down (the rollercoaster is paid for with equity) and you have to figure out how. There are some fixed things provided such as: Revenue comes through tickets purchased, restaurants, games, food vendors A 5% coupon is offered when you make your first in-park purchase after the ticket and can be used on any later purchase that day You have data tracking on most things, but have lost all $ values of receipts from restaurants, vendors, games, etc. Tickets are half price after 4 pm. Create an analysis to determine why revenue has fallen.

Question 4

Case Interview #2 This case is about contest sizing. Essentially, DraftKings has to provide a prize pool guarantee upfront, and thus needs to get as close to maxing out a tournament as possible without undersizing (as to lose out on demand). Work through the proper sizing of a new tournament offering.
