In this section, we’ll review the various interview questions that might be asked during a Data Analyst interview at GoodRx. The interview process will likely focus on your analytical skills, experience with SQL, and ability to derive insights from data. Be prepared to discuss your previous projects, how you approach problem-solving, and your understanding of key metrics that drive business decisions.

SQL and Data Management

1. Can you explain the difference between INNER JOIN and LEFT JOIN in SQL?

Understanding SQL joins is crucial for data analysts, as they are fundamental for data retrieval from multiple tables.

How to Answer

Explain the basic definitions of INNER JOIN and LEFT JOIN, and provide a scenario where each would be used.

Example

"An INNER JOIN returns only the rows where there is a match in both tables, while a LEFT JOIN returns all rows from the left table and the matched rows from the right table. For example, if I have a table of customers and a table of orders, an INNER JOIN would show only customers who have placed orders, whereas a LEFT JOIN would show all customers, including those who haven't placed any orders."

2. How would you optimize a slow-running SQL query?

Performance optimization is key in data analysis, especially when dealing with large datasets.

How to Answer

Discuss techniques such as indexing, query restructuring, and analyzing execution plans.

Example

"I would start by checking the execution plan to identify bottlenecks. If I see that certain columns are frequently filtered, I would consider adding indexes on those columns. Additionally, I would look for opportunities to simplify the query by removing unnecessary joins or subqueries."

3. Describe a complex SQL query you have written. What was its purpose?

This question assesses your practical experience with SQL.

How to Answer

Provide a specific example, detailing the complexity and the outcome of the query.

Example

"I once wrote a complex SQL query to analyze customer purchase patterns over a year. It involved multiple joins across customer, order, and product tables, along with window functions to calculate running totals. The insights helped the marketing team tailor their campaigns based on customer behavior."

4. What are Common Table Expressions (CTEs) and when would you use them?

CTEs can simplify complex queries and improve readability.

How to Answer

Define CTEs and explain their benefits, including when to use them.

Example

"CTEs are temporary result sets that can be referenced within a SELECT, INSERT, UPDATE, or DELETE statement. I use them to break down complex queries into simpler parts, making it easier to read and maintain. For instance, I used a CTE to first filter a dataset before performing aggregations, which improved the clarity of my SQL code."

Data Analysis and Interpretation

1. How do you approach a new data analysis project?

This question evaluates your analytical thinking and project management skills.

How to Answer

Outline your process from understanding the problem to delivering insights.

Example

"I start by clearly defining the objectives and key questions of the analysis. Then, I gather and clean the relevant data, ensuring its quality. After that, I perform exploratory data analysis to identify trends and patterns, followed by applying statistical methods to derive insights. Finally, I present my findings in a clear and actionable format."

2. Can you give an example of how you used data to influence a business decision?

This question assesses your ability to translate data insights into actionable business strategies.

How to Answer

Share a specific instance where your analysis led to a significant decision.

Example

"In my previous role, I analyzed customer feedback data and identified a recurring issue with our product's usability. I presented my findings to the product team, which led to a redesign that improved user satisfaction scores by 30%."

3. What metrics do you consider most important when evaluating a marketing campaign?

Understanding key performance indicators (KPIs) is essential for a data analyst in a marketing context.

How to Answer

Discuss relevant metrics and their significance in measuring campaign success.

Example

"I focus on metrics such as conversion rate, customer acquisition cost, and return on investment. For instance, while evaluating a recent campaign, I found that although the reach was high, the conversion rate was low, indicating a need for better targeting or messaging."

4. How do you handle missing or incomplete data in your analysis?

This question tests your problem-solving skills and understanding of data integrity.

How to Answer

Explain your strategies for dealing with missing data, including imputation methods or data exclusion.

Example

"I first assess the extent and pattern of the missing data. If it's minimal and random, I might exclude those records. For larger gaps, I consider using imputation techniques, such as mean or median substitution, or even predictive modeling to estimate missing values, depending on the context of the analysis."

Statistical Knowledge

1. Explain the concept of p-value in hypothesis testing.

Statistical knowledge is crucial for data analysts, especially in interpreting results.

How to Answer

Define p-value and its role in hypothesis testing.

Example

"The p-value measures the probability of obtaining results at least as extreme as the observed results, assuming the null hypothesis is true. A low p-value (typically < 0.05) indicates strong evidence against the null hypothesis, suggesting that we may reject it."

2. What is the difference between Type I and Type II errors?

Understanding errors in hypothesis testing is fundamental for data analysis.

How to Answer

Define both types of errors and provide examples.

Example

"A Type I error occurs when we incorrectly reject a true null hypothesis, while a Type II error happens when we fail to reject a false null hypothesis. For example, in a clinical trial, a Type I error would mean concluding a treatment is effective when it is not, whereas a Type II error would mean failing to detect an effective treatment."

3. How do you determine if a dataset is normally distributed?

Normal distribution is a common assumption in many statistical tests.

How to Answer

Discuss methods for assessing normality, such as visualizations and statistical tests.

Example

"I would use visual methods like histograms or Q-Q plots to visually assess normality. Additionally, I might apply statistical tests like the Shapiro-Wilk test to quantitatively evaluate the normality of the dataset."

4. Can you explain the concept of correlation versus causation?

Understanding the difference is crucial for data interpretation.

How to Answer

Define both terms and explain their relationship.

Example

"Correlation indicates a relationship between two variables, but it does not imply that one causes the other. For instance, ice cream sales and drowning incidents may be correlated, but that does not mean ice cream consumption causes drowning; both may be influenced by a third variable, such as warm weather."
