6. Let’s say that you’re playing a dice game, and you have two dice. What is the probability of rolling at least one 3?

In the sports betting industry and sports fantasy, there are numerous use cases that can be solved through the application of probability concepts. As an example, probability enables Business Analysts to quantify the likelihood of various betting strategies to maximize long-term profits. Therefore, aspiring Business Analysts need to have a solid understanding of probability concepts.

How to Answer

You need to calculate the probability of rolling at least one 3 using basic probability principles, considering all possible outcomes of rolling two dice. Also, provide a brief explanation of your calculation method and reasoning behind the probability value obtained.

Example

“To calculate the probability of rolling at least one 3 with two dice, we first determine the total number of possible outcomes when rolling two dice, which is 36 (6 sides on each die, resulting in 6 * 6 = 36 possible combinations). Next, we identify the number of favorable outcomes, where at least one die shows a 3. There are 11 such outcomes: (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (1,3), (2,3), (4,3), (5,3), and (6,3). Therefore, the probability of rolling at least one 3 is ¹¹⁄₃₆ or approximately 0.3056, which can also be expressed as 30.56%.”

7. You buy a scalped ticket at the stadium that has a 20% chance of not working. However, you need to buy a $70 box office ticket if your scalped ticket doesn’t work. What’s the expected value of this situation?

When you’re applying for a Business Analyst position, DraftKings expects you to understand how to assess risks, as sports betting is one of their main focuses. Knowing the theory of expected value will also help you to assess the potential outcomes of different betting strategies.

How to Answer

As a first step, calculate the expected value (EV) of the situation by considering the probability of each outcome and the associated payoffs. Next, multiply each payoff by its corresponding probability and finally sum the results to find the EV.

Example

“To calculate the expected value of the situation, we first need to take a look at the probability of a scalped ticket working, which is 80%, and not working, which is 20%. If the scalped ticket works, we don’t need to spend anything. If it doesn’t work, we spend an additional $70 on a box office ticket. Therefore, the expected value can be calculated as: (0.8 * X) + (0.2 * (X + $70)), where X is the price of a scalped ticket.”

8. Let’s say you have to analyze the results of an A/B test. One variant of the A/B test has a sample size of 50K users, and the other has a sample size of 200K users. Given the unbalanced size between the two groups, can you determine if the test will result in a bias towards the smaller group?

To make informed decisions and findings based on data, a Business Analyst should understand the theory of statistics. This is especially true at DraftKings, where you need to continuously test new features of fantasy sports on customer behavior. This question assesses your ability to make accurate findings regarding A/B testing that will be implemented a lot at DraftKings.

How to Answer

First, explain the concept of bias in A/B testing and how sample size imbalances can potentially introduce bias towards the smaller group. Then, start to discuss strategies for mitigating bias in A/B tests with unequal sample sizes, such as adjusting the analysis method or implementing statistical techniques like weighting or propensity score matching.

Example

“In A/B testing, bias refers to the systematic favoritism towards one variant over the other due to factors unrelated to the treatment itself. When there is a significant difference in sample sizes between the two variants, there is a potential for bias towards the smaller group. This is because statistical inference may be influenced more by the larger sample size. To mitigate bias in this scenario, we can consider adjusting the analysis method to account for the sample size difference or implementing statistical techniques like weighting or propensity score matching.”

9. What methods do you use to ensure accurate data analysis and data visualizations?

Delivering an accurate and reliable analysis is one of the main tasks of a Business Analyst, especially in an industry where decisions are made based on data-driven insights like DraftKings. This question will assess your approach to presenting an analysis and how you deal with anomalies in the data.

How to Answer

First, start by discussing the methods you’ll use to ensure the accuracy and reliability of your analysis and visualization, such as data validation, thorough testing, peer review, etc. Next, don’t forget to highlight the importance of using credible data sources and employing robust statistical techniques to minimize errors and biases. Also, don’t forget to emphasize the significance of transparency in your analysis process, such as by documenting assumptions, methodologies, and limitations.

Example

“Based on my experience in my previous role, I would meticulously validate data sources, perform thorough testing of analytical models, and incorporate peer review feedback to ensure accuracy. I follow best practices in data analysis and visualization, ensuring that statistical techniques are applied appropriately and biases are minimized. Additionally, I prioritize transparency by documenting assumptions, methodologies, and limitations, which allows the managers and stakeholders to understand and trust the results of my analysis.”

10. Let’s say we want to launch a re-design of a landing page to improve the click-through rate. We can do this by implementing an A/B test. Given that we launch an A/B test, how would you infer if the results of the click-through rate were statistically significant or not?

A/B testing is continuously conducted at DraftKings to improve their product and increase customer engagement. Therefore, be prepared to answer some questions about this, and don’t forget to level up your knowledge about this topic. The interviewer wants to assess if you have the skills to understand the concept of A/B testing and can make accurate findings based on the observation.

How to Answer

First, explain the concept of statistical significance in the context of A/B testing and its importance in determining whether observed differences in click-through rates are due to genuine effects or random chance. Then, discuss common statistical methods used to assess statistical significance in A/B testing, such as hypothesis testing (e.g., using t-tests or z-tests) and calculating confidence intervals. Next, outline the steps involved in evaluating A/B test results for statistical significance, including defining null and alternative hypotheses, selecting an appropriate significance level (e.g., α = 0.05), and conducting statistical tests.

Example

“In the context of launching a re-design of a landing page to improve the click-through rate through an A/B test, determining whether the observed differences in click-through rates are statistically significant is crucial. Statistical significance indicates that the differences observed in click-through rates between the control and variant groups are unlikely to have occurred by random chance. We typically assess statistical significance using hypothesis testing, where we define null and alternative hypotheses, select a significance level (e.g., α = 0.05), and conduct statistical tests such as t-tests or z-tests. If the p-value obtained from the test is less than the significance level, we reject the null hypothesis and conclude that the observed differences are statistically significant.”

11. Which BI tools are you familiar with?

If you’d like to work as a Business Analyst at any company, be prepared to be asked this question. This is because your main task as a Business Analyst will be to analyze data and present your analysis to different managers and stakeholders. You need to use different technology stacks to be able to do the task.

How to Answer

Start by listing all the BI tools you are familiar with, and it’s better if those tools are also mentioned in the job description. Next, provide brief explanations of your experience with each tool by telling them about any relevant projects you’ve completed using them. Also, don’t forget to highlight your ability to adapt to new tools and learn quickly if necessary.

Example

“I am proficient in two BI tools, such as Tableau and Power BI. In my previous role, I used Tableau extensively to visualize performance metrics that help stakeholders make informed business decisions. I also have experience with Power BI, where I created interactive dashboards to monitor key performance indicators in real time. I have a strong interest in and I’m prepared to learn new BI tools to excel in any role I’m in.”

12. Given a table called ‘transactions’, which has user id, date, product id, and quantity, write a SQL query to sample every 4th row of product id ordered by the date?

When applying for a Business Analyst position at DraftKings, you’re expected to already know the basics of SQL. This is because the data at DraftKings are huge in size and volume, which means you’ll be ingesting data that you need to analyze mainly with SQL queries. Therefore, make sure that you also level up your SQL skills before applying.

How to Answer

When dealing with an SQL question, make sure that you read the question carefully. Take a closer look at the input table and the data type of each column, as well as the expected output.

For this question, it’s necessary to use a subquery to assign row numbers to each row in the ‘transactions’ table after we order them according to date. Since we want to sample every 4th order, we can use a WHERE clause.

Example

“Since we want to fetch the product id according to the ordered date from the ‘transactions’ table, then we use a SELECT … FROM transactions clause to fetch both variables. Next, since we want to order the output by date, then we can use an ORDER BY clause at the end of the query. To sample every 4th row, we can use a WHERE clause. Finally, we can utilize the subquery concept to assign row numbers to each row after we order them according to the data. Below is the complete SQL query:”

SELECT created_at, product_id

FROM (

SELECT created_at, product_id,

ROW_NUMBER() OVER (ORDER BY created_at) AS row_num

	FROM transactions

) AS numbered_rows

WHERE row_num % 4 = 0

ORDER BY created_at;

13. What is the expected value of a die roll?

As an aspiring Business Analyst, mastering the theory of expected value can make you a valuable asset for companies like DraftKings. This knowledge allows you to assist the company in designing betting strategies that maximize long-term profits and evaluating the risk associated with various betting strategies. This, in turn, enhances client trust and engagement with the company.

How to Answer

First, you need to mention what the expected value of a die roll means, which is the average value that can be expected over many rolls, considering all possible outcomes and their probabilities. Next, start to calculate the expected value of a fair six-sided die by summing the products of each outcome (1 through 6) and its probability (¹⁄₆ for each outcome).

Example

“The expected value of a die roll is calculated by summing the products of each outcome (1 through 6) and its probability (¹⁄₆ for each outcome). Therefore, for a fair six-sided die, the expected value is (¹⁄₆ * 1) + (¹⁄₆ * 2) + (¹⁄₆ * 3) + (¹⁄₆ * 4) + (¹⁄₆ * 5) + (¹⁄₆ * 6) = 3.5. This means that, on average, we can expect a roll of a fair die to result in a value of 3.5.”

14. Let’s say that you work for a SAAS company and a PM comes up to you and tells you that users that come from Country X convert from a free trial to paying at a much higher rate than users from Country Y. What would you investigate further to determine why this was happening?

If you would like to become a Business Analyst at DraftKings, be prepared to get a business case-study question like this. With this question, people at DraftKings would like to assess your critical thinking and problem-solving skills. The main goal is not to get the correct solution, but to walk them through your thought process of how you come up with the solution.

How to Answer

First, identify potential factors that could influence the difference in conversion rates, such as cultural differences, economic factors, user demographics, or product-specific features. Then, propose hypotheses based on these factors and suggest investigative approaches to test and validate these hypotheses. Finally, don’t forget to recommend potential actions or experiments to address any identified issues or capitalize on opportunities to improve conversion rates for users from Country Y.

Example

“To determine why users from Country X are converting from free trials to paying at a higher rate than users from Country Y, I would first explore potential factors contributing to this discrepancy. These factors could include cultural differences, economic conditions, user demographics, or differences in product features or marketing strategies targeted at each country.

To investigate further, I would conduct a comprehensive analysis of user data, segmenting users by country and analyzing their behavior throughout the user journey, from signing up for a free trial to converting to a paying customer. I would also test different product features, marketing messages, or pricing strategies tailored to users from Country Y and see their impact on conversion rates with A/B testing.”

15. What is your step-by-step approach of cleaning the data?

Data cleaning is a mandatory step every Business Analyst should do before analyzing data any further in any data analysis project. This question assesses your understanding of different kinds of data cleaning techniques to ensure that you’re able to present comprehensive and accurate results from your data.

How to Answer

First, mention the common approach to data cleaning, including steps such as identifying and handling missing values, removing duplicates, correcting inconsistencies, validating data integrity, etc. Next, emphasize the importance of understanding the data domain and business context to inform data cleaning decisions effectively.

Example

“My approach to data cleaning involves several steps. First, I conduct data profiling to understand the structure and quality of the data. Then, I identify and handle missing values using techniques like imputation or deletion based on the nature of the data and business requirements. Next, I address duplicates and inconsistencies by performing deduplication and data standardization. Throughout the process, I use tools such as Excel, Python, or SQL scripts to automate repetitive cleaning tasks and ensure efficiency.”

16. What are the Z and t tests and what is the difference between them?

This question assesses your knowledge on how to properly conduct hypothesis testing. Each test has specific conditions that need to be fulfilled and knowing the difference between these two would make an impact on the accuracy of the findings. If you want to be a Business Analyst at DraftKings, make sure to brush up your inferential statistics skill to be able to distinguish between different variations of hypothesis testing.

How to Answer

Begin by explaining what Z and t tests are and their primary purposes in statistical hypothesis testing. Next, describe the scenarios in which each test is typically used and the key differences between them, such as the assumptions they make and the sample size requirements. Then, segue to mention the circumstances under which one test may be preferred over the other, such as when the population standard deviation is known or when dealing with small sample sizes.

Example

“Z and t tests are both statistical hypothesis tests used to assess the significance of observed differences between sample means or proportions. The Z test is typically used when the population standard deviation is known, or the sample size is large, while the t-test is used when the population standard deviation is unknown, or the sample size is small.

For example, let’s say that we want to perform A/B testing where we compare the performance of different website versions or marketing campaigns. In this scenario, we might use a t-test to determine if there is a statistically significant difference in conversion rates between two groups of users exposed to different conditions. If the sample size is large or the population standard deviation is known, a Z-test could be more appropriate.”

17. What is your approach when you need to visualize data with a large number of variables?

When applying for a Business Analyst position at DraftKings, proficiency in data visualization is expected. However, when dealing with datasets containing numerous variables, effective visualization becomes challenging. As a result, you are required to possess the skills necessary to visualize and present key variables in complex datasets.

How to Answer

First, start by describing your approach to visualizing data with a large number of variables by emphasizing techniques for simplifying and summarizing complex information. Next, highlight the use of visualization tools and techniques such as dimensionality reduction, clustering, and hierarchical grouping to organize data effectively. Don’t forget to also emphasize the importance of selecting appropriate visualization types (e.g., scatter plots, heatmaps, treemaps) based on the data characteristics and analysis goals.

Example

“When dealing with a large number of variables, my approach focuses on simplifying and summarizing the data. I normally use techniques such as dimensionality reduction such as principal component analysis (PCA) or t-distributed stochastic neighbor embedding (t-SNE) to reduce the number of variables while preserving key information of the data.

Additionally, I might also implement clustering algorithms to group similar variables together, making it easier to identify patterns and relationships.

When selecting visualization types, I consider the data characteristics and analysis goals to choose the most appropriate charts or graphs, such as scatter plots for exploring relationships or heatmaps for visualizing correlations.”

18. Let’s say you’re working with survey data sent in the form of multiple choice questions. How would you test if survey responses were filled at random by certain individuals, as opposed to truthful selections?

One of the most fundamental prerequisites of comprehensive statistical analysis is by making sure that the samples’ quality is on point and they’re obtained by random. It is the task of a Business Analyst to assess the data quality before making an insight based on it. In this question, people at DraftKings want to assess your ability to handle uncertainty in the quality of the data that you work on.

How to Answer

Start by explaining the importance of detecting random responses in survey data and its implications for data quality and decision-making. Next, start to discuss various statistical methods or techniques that can be used to test if survey responses were filled randomly, such as chi-square tests, frequency analysis, or outlier detection methods. Don’t forget to also mention additional investigative approaches that could be employed to understand why random responses may be occurring, such as reviewing survey design or identifying patterns in response patterns.

Example

“Detecting whether survey responses were filled randomly by certain individuals is crucial for maintaining data integrity and ensuring the validity of insights derived from survey data. One common approach to test for randomness in survey responses is by using statistical methods such as chi-square tests or frequency analysis. These tests compare the observed frequency distribution of responses to the expected distribution under the assumption of randomness.

For example, we could use a chi-square goodness-of-fit test to compare the observed frequency of responses for each multiple-choice question to the expected frequency distribution assuming random selection. If the test results in a statistically significant difference between the observed and expected distributions, it suggests that responses may not be random.

Additionally, we should also do further investigation to identify potential factors that are influencing the randomness of the responses. This can be done by examining the wording and structure of survey questions, evaluating the incentives provided for survey participation, or investigating the timing and method of survey distribution.”

19. Can you walk us through your process to determine which type of visualization to use for a given dataset?

As a Business Analyst at DraftKings, the ability to choose appropriate data visualization according to the characteristics of the data is crucial. This question assesses your understanding of different data visualization charts and the scenario in which you can implement them.

How to Answer

First, describe the first thing that you look at when determining which data visualization to use, such as the characteristics of the dataset or the analysis goals. Next, explain how you consider factors such as data type, distribution, relationships, and audience preferences when selecting visualization techniques.

Example

“My process begins by understanding the dataset and analysis goals, including the type of data (whether a variable is categorical or numerical), the distribution of variables, and the relationships among them. Based on these factors, I consider the most suitable visualization types. As an example, I would consider bar charts for comparing categorical variables, line charts for showing trends over time, or scatter plots for exploring relationships between numerical variables. I also take into account the audience’s preferences and the context of the analysis to ensure that the visualizations are engaging and informative.”

20. Let’s say we’re given a biased coin that comes up heads 30% of the time when tossed. What is the probability of the coin landing as heads exactly 5 times out of 6 tosses?

Knowing different types of probability distributions and when to apply them is crucial for Business Analysts. When working at DraftKings, you’ll be presented with use cases which require probability knowledge, for example when they design new algorithms to compute the probability of a particular outcome of a sport event. Knowing which probability distribution that suits a particular scenario best would help you to make comprehensive risk assessments to clients or stakeholders.

How to Answer

When dealing with a probability question, make sure that first you understand the input that you have and the objective. Explain that with the scenario of a biased coin, we can use the binomial probability formula to calculate the probability of the coin landing heads exactly 5 times out of 6 tosses.

Example

“We have a scenario with a biased coin that lands heads 30% of the time. The objective is to calculate the probability of this coin landing heads exactly 5 times out of 6 tosses.

We can solve this problem using binomial distribution. The formula for this probability distribution is as follows:

P(X=k) = (n \choose k) * p^k * (1-p)^(n-k),

where n is the number of trials, k is the number of successes, and p is the probability of success. Plug in the values that we have into the formula, we get:

P(5 heads out of 6 tosses) = (6 \choose 5) * (0.3)^5 * (0.7)^(6-5)

= 6 * (0.3)^5 * (0.7)

≈ 0.08829

This probability indicates that there’s an approximately 8.83% chance of the biased coin landing heads exactly 5 times out of 6 tosses.”

21. In a casino dice game, where you can either keep the result of your first roll or reroll to earn the second roll’s value, what is the expected amount of money you’d win if you adopt a profit-maximizing strategy?

In the context of a casino dice game, understanding and applying probability concepts is crucial for maximizing potential winnings. For instance, by analyzing the expected value of rerolling a die versus keeping the initial roll, players can adopt a profit-maximizing strategy. This decision-making process hinges on comparing the expected value of a second roll against the value of the initial roll, which can be quantified through probability calculations.

How to Answer

You need to assess the expected value of the first roll and determine whether rerolling is the optimal choice based on that value. The strategy involves calculating the average outcome of a die roll (which is 3.5) and deciding to reroll if the initial roll is below this threshold. Additionally, provide a brief explanation of how the expected value influences the decision to reroll and the reasoning behind the final expected monetary value.

Example

“To determine the optimal strategy, we first calculate the expected value of a single die roll, which is 3.5. This is obtained by summing all possible outcomes (1 through 6) and dividing by the number of outcomes (6). If the first roll results in a value of 1, 2, or 3, it is statistically advantageous to reroll because the expected value of the second roll is higher (3.5). Conversely, if the first roll is 4, 5, or 6, the player should keep the initial roll, as it offers a higher or equal value compared to the expected value of rerolling. By adopting this strategy, the overall expected monetary value is 4.25, calculated as the average of the two scenarios.”

22. You pull two cards, one at a time, from a deck of cards without replacement. What is probability that the second card you pick has a different color or different suit than the first card?

In card games and probability-based decision-making scenarios, understanding the likelihood of various outcomes is essential for optimizing strategies. For instance, when pulling cards from a deck, calculating the probability of drawing a card with a different color or suit than the first card can significantly impact gameplay decisions. By breaking down the problem into specific cases, players can better anticipate outcomes and make informed choices.

How to Answer

You need to calculate the probability of pulling a second card that has a different color or suit than the first card using basic probability principles. Consider the total number of cards remaining after the first draw and analyze the likelihood of pulling a card that meets the condition. Provide a brief explanation of your calculation method and the reasoning behind the probability value obtained.

Example

“To calculate the probability of pulling a second card with a different color or suit, consider two cases. First, if the first card drawn is red, the probability of pulling a black card next is ²⁶⁄₅₁, as there are 26 black cards remaining out of 51. In the second case, pulling a card with a different suit has a probability of ³⁹⁄₅₁, since 39 cards of a different suit remain out of the 51 total. Therefore, the overall probability of pulling a second card with a different color or suit is ³⁹⁄₅₁, or approximately 0.7647, which can also be expressed as 76.47%.”

As you’ve seen from the list of questions above, the interview process at DraftKings for a Business Analyst position demands a strong understanding of analytical principles, problem-solving capabilities, and familiarity with the sports entertainment industry.
