Business Data Analyst Interview Questions

826 business data analyst interview questions shared by candidates

An expected value problem. There was a bag with $1, $5, $10 or $20 bills inside of it. The question was four parts, each of which asked for the expected value of the bill you would pull out of the bag. Each part added a twist, such as if you had the option to pull a bill out, put it aside and try again would you, and when would you not? Relatively simple stuff.

Phone screen #1: What are the odds 4 different people would have birthdays in unique seasons? Quant Case: How much would you be willing to pay to play a game where you pick one bill out of a bag with equal proportions of $10, $20, $50, $100 bills? What if you got to put your bill back and pick a second time? What if you could pick a third time? What if you could remove all of the $10 bills before you picked? Business Case: You own a local coffee shop. You notice your profits are down over the last week. Walk me through the process of isolating what the problem is. In Office case 1: Contest sizing In office case 2: similar to the coffee shop question but with trains. The city that operates the train network sent out a survey about customer satisfaction, and an overwhelming number of people selected the dropdown option "queues and delays" as their main complaint. Walk through the potential sources of the problem. Behavioral in office: went through resume, elevator pitch "tell me about yourself", relevant work experience, why you want to work at DraftKings, etc.
