Strava Data Analyst Interview Questions

In this section, we’ll review the various interview questions that might be asked during a Strava data analyst interview. The interview will focus on your analytical skills, statistical knowledge, and ability to derive insights from data. Be prepared to discuss your experience with SQL, probability, and analytics, as well as how you can apply these skills to enhance user experience and product development at Strava.

Statistics

1. Can you explain the difference between descriptive and inferential statistics?

Understanding the distinction between these two branches of statistics is crucial for data analysis.

How to Answer

Describe how descriptive statistics summarize data, while inferential statistics allow you to make predictions or inferences about a population based on a sample.

Example

“Descriptive statistics provide a summary of the data, such as mean and standard deviation, which helps in understanding the dataset. In contrast, inferential statistics use sample data to make generalizations about a larger population, such as estimating population parameters or testing hypotheses.”

2. How do you handle missing data in a dataset?

Handling missing data is a common challenge in data analysis.

How to Answer

Discuss various techniques such as imputation, deletion, or using algorithms that support missing values, and explain your reasoning for choosing a particular method.

Example

“I typically assess the extent of missing data first. If it’s minimal, I might use mean imputation. For larger gaps, I prefer to analyze the data patterns and consider using predictive models to estimate missing values, ensuring that the integrity of the dataset is maintained.”

3. What statistical tests would you use to compare two groups?

This question assesses your knowledge of hypothesis testing.

How to Answer

Mention common tests like t-tests or ANOVA, and explain when to use each based on the data characteristics.

Example

“I would use a t-test if I’m comparing the means of two independent groups, as it’s suitable for small sample sizes. If I have more than two groups, I would opt for ANOVA to determine if there are any statistically significant differences among the group means.”

4. Explain the concept of p-value and its significance in hypothesis testing.

Understanding p-values is essential for interpreting statistical results.

How to Answer

Define p-value and discuss its role in determining the strength of evidence against the null hypothesis.

Example

“A p-value indicates the probability of observing the data, or something more extreme, if the null hypothesis is true. A smaller p-value suggests stronger evidence against the null hypothesis, typically leading to its rejection if it falls below a predetermined significance level, such as 0.05.”

Probability

1. How would you explain the concept of conditional probability?

This question tests your understanding of probability theory.

How to Answer

Define conditional probability and provide an example to illustrate its application.

Example

“Conditional probability measures the likelihood of an event occurring given that another event has already occurred. For instance, the probability of a user completing a workout may depend on whether they have previously engaged with the app, which can be calculated using the formula P(A|B) = P(A and B) / P(B).”

2. Can you describe a situation where you applied probability in your analysis?

This question allows you to showcase practical application of your knowledge.

How to Answer

Share a specific example where you used probability to inform a decision or analysis.

Example

“In a previous project, I analyzed user engagement data and used probability to predict the likelihood of users returning to the app after their first workout. By segmenting users based on their initial activity levels, I was able to identify key factors that influenced retention rates.”

SQL

1. How do you optimize a slow-running SQL query?

This question assesses your SQL skills and problem-solving abilities.

How to Answer

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

Example

“To optimize a slow-running SQL query, I would first analyze the execution plan to identify bottlenecks. Then, I might add indexes to frequently queried columns, rewrite the query to reduce complexity, or break it into smaller parts to improve efficiency.”

2. Can you explain the difference between INNER JOIN and LEFT JOIN?

Understanding SQL joins is fundamental for data manipulation.

How to Answer

Define both types of joins and explain their differences in terms of data retrieval.

Example

“An INNER JOIN returns only the rows that have matching values in both tables, while a LEFT JOIN returns all rows from the left table and the matched rows from the right table, filling in NULLs for non-matching rows. This distinction is crucial when determining how to combine datasets effectively.”

Analytics

1. Describe a project where you used data analytics to drive business decisions.

This question allows you to demonstrate your analytical impact.

How to Answer

Share a specific project, the data analysis techniques you used, and the outcomes of your work.

Example

“In my last role, I analyzed user behavior data to identify trends in app usage. By applying regression analysis, I discovered that users who engaged with community features were 30% more likely to remain active. This insight led to the development of new community-driven features, significantly increasing user retention.”

2. How do you prioritize which metrics to track for a new product feature?

This question assesses your ability to align analytics with business goals.

How to Answer

Discuss your approach to identifying key performance indicators (KPIs) based on user needs and business objectives.

Example

“I prioritize metrics by first aligning them with the overall business goals and user needs. I conduct stakeholder interviews to understand what success looks like for the feature, then select KPIs that provide actionable insights, such as user engagement rates and conversion metrics.”
