How to Answer

Discuss a specific instance where you identified a problem, proposed a solution, and implemented it successfully. Highlight the impact it had on the team or organization.

Example

“In my last role, I noticed that our reporting process was taking too long due to manual data entry. I proposed automating the data collection using SQL scripts, which reduced the reporting time by 50% and allowed the team to focus on analysis rather than data gathering.”

Technical Skills

Understanding statistical methods is crucial for a Data Analyst role, especially in a data-driven company like Chime.

How to Answer

Mention specific statistical methods you have used, such as regression analysis, hypothesis testing, or A/B testing, and explain how they helped you derive insights.

Example

“I frequently use regression analysis to understand the relationship between different variables. For instance, I applied it to analyze how changes in our marketing spend affected user acquisition rates, which helped us optimize our budget allocation.”

3. How do you ensure data integrity in your analyses?

Data integrity is vital for making informed decisions, and Chime will want to know your approach to maintaining it.

How to Answer

Discuss the steps you take to validate data, such as cross-referencing with other sources, using data cleaning techniques, and implementing checks throughout your analysis process.

How to Answer

Provide examples of complex queries you have written, including joins, subqueries, and aggregations, and explain how they contributed to your analysis.

Example

“I have extensive experience with SQL, including writing complex queries to extract insights from large datasets. For example, I created a query that combined user behavior data with marketing campaign data to analyze conversion rates, which led to actionable recommendations for our marketing strategy.”

Data Visualization

Problem-Solving and Communication

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

Chime will want to understand your methodology and how you tackle challenges.

How to Answer

Outline your process from defining the problem, gathering data, analyzing it, and presenting your findings. Emphasize your structured approach.

As you prepare for your interviews, consider the types of questions that may arise in each of these stages.

1. How would you set up an A/B test to optimize button color and position for higher click-through rates?

A team wants to A/B test multiple changes in a sign-up funnel. For instance, they want to see if changing a button from red to blue and/or from the top to the bottom of the page will increase click-through rates. How would you set up this test?

2. Why are job applications decreasing despite steady job postings?

You are analyzing the metrics of a job board and notice that while the number of job postings per day has remained constant, the number of applicants has been steadily decreasing. Why might this be happening?

3. Can unbalanced sample sizes in an A/B test result in a bias towards the smaller group?

You need to analyze the results of an A/B test, with one variant having a sample size of 50K users and the other having 200K users. Can the unbalanced sizes lead to bias towards the smaller group?

4. How can you check if the assignment to A/B test buckets was truly random?

In an A/B test, how would you verify that the assignment to various buckets was truly random?

5. How would you assess the validity of an A/B test result with a 0.04 p-value?

6. What are time series models, and why are they needed over simpler regression models?

Explain what time series models are and discuss why they are necessary when simpler regression models might not suffice.

7. What happens when you run logistic regression on perfectly linearly separable data?

Given a perfectly linearly separable dataset, describe the outcome of running logistic regression on it.

8. What is the probability of rolling at least one 3 with 2 dice?

9. Can an AB test with unbalanced sample sizes result in a bias towards the smaller group?

Analyze the potential bias in an AB test where one variant has 50K users and the other has 200K users due to the unbalanced sample sizes.

10. What happens to the target metric after applying a new UI that won by 5% in an AB test?

If a new UI tested on a random subset of users wins by 5% on the target metric, predict the change in the metric after applying the new UI to all users, assuming no novelty effect.

11. What are the key differences between classification models and regression models?

Explain the primary distinctions between classification and regression models, focusing on their objectives, output types, and typical use cases.
