Overview of the Earnest Research Hiring Process

Before diving into specific questions, it’s helpful to understand the overall flow of Earnest’s hiring process. Here’s what you can generally expect

  • Initial Screening Call: A 30 minute phone or video call with an HR representative or hiring manager. This is focused on assessing your resume, experience, and motivation for the role.

  • 1-on-1 Interviews: A series of 60-90 minute behavioral and technical interviews with various team members including senior leadership.

  • Case Study: Many roles involve analyzing a data set or business case and presenting recommendations. This evaluates your analytical approach and communication skills.

  • Reference and Background Checks: Earnest conducts extensive vetting as a final step before making offers.

The process is described as rigorous but fair and transparent. It can span 1-2 months from initial call to offer. Thorough preparation is key to navigating each stage smoothly. Now let’s examine the kinds of questions you’re likely to encounter.

The 16 Most Common Earnest Research Interview Questions

1. Walk me through a complex data analysis project you led. What insights did you uncover and how did they influence business decisions?

This question assesses your ability to derive strategic insights from complex data and clearly communicate recommendations that drive business impact. When responding, be sure to:

  • Describe the business context and goals of the project. What problem were you trying to solve?

  • Explain the data sources, volume, and complexity involved.

  • Discuss your methodology and analytic approach. How did you clean, analyze, and interpret the data?

  • Share the key insights and trends you uncovered that were most relevant to the goals.

  • Explain how your insights directly influenced or changed strategic business decisions. Quantify the impact if possible.


“As a pricing analyst for an e-commerce company, I led a project analyzing 5 years of transaction data from our US site to optimize our pricing strategy. The data spanned over 10 million transactions across thousands of products. I leveraged SQL, Python, and statistical methods like regression to clean the large data set and uncover pricing insights.

My analysis identified that products with price points ending in .99 had 13% higher conversion rates when compared to rounded numbers. Additionally, I found that raising prices by 3% during peak demand periods did not negatively impact conversion rates.

These insights led our executive team to implement .99 pricing across the catalog during regular seasons and dynamically adjust prices based on demand forecasts. This pricing strategy increased revenue by over 5% in the first year without any loss in transaction volume.”

2. How would you explain a complex data analytics concept to a non-technical executive stakeholder?

This question tests your ability to translate complex technical details into simple, business-focused terms that resonate with non-technical audiences. When answering:

  • Avoid using jargon or technical language. Explain concepts simply.

  • Use analogies and relatable examples to explain complex methodologies.

  • Emphasize the business implications/benefits over granular technical details.

  • Ask questions to gauge the stakeholder’s level of understanding and tailor your explanation accordingly.


“I would avoid using technical jargon and instead focus on explaining the core business insight that our analytics uncovered. For example, rather than dive into the details of my sentiment analysis methodology, I would say:

‘By utilizing advanced analytics, we identified that approximately 40% of comments on social media about Product X were negative due to complaints about missing features. This indicates an opportunity to enhance customer satisfaction by prioritizing these requested features in the next product update. Doing so could increase referrals and retention.’

I would then use an analogy like taking the temperature of a room to characterize sentiment analysis at a high-level. Finally, I’d invite questions from the stakeholder to ensure my explanation was clear and focused on their key priorities.”

3. How would you test and validate a new predictive algorithm before full implementation?

This question gauges your critical thinking skills in evaluating the suitability of an analytical model or algorithm. When responding, be sure to discuss:

  • Comparing the new algorithm’s performance to benchmarks or existing solutions using metrics like accuracy and runtime.

  • Testing the algorithm on sample datasets that resemble real-world conditions.

  • Checking for sound logical assumptions within the algorithm.

  • Assessing for potential biases or overfitting through statistical techniques.

  • Evaluating unintended consequences through scenario testing.

  • Explaining how you would address issues or limitations discovered through testing.


“Before full implementation, I would thoroughly test the new predictive algorithm by benchmarking its performance against existing models using metrics like precision, recall, and AUC ROC. I would run tests on a variety of sample datasets that cover likely real-world scenarios to ensure robust performance despite variability.

Additionally, I would have our data scientists peer review the algorithm logic for sound assumptions and minimize biases through techniques like cross-validation. Using tools like LIME and SHAP, I would evaluate model explainability and check for signs of overfitting or unintended discrimination.

If limitations were discovered, I would devise a plan to refine the algorithm accordingly. Perhaps additional data samples, feature engineering, or parameter tuning would resolve the issues. Extensive validation is crucial to ensure our new algorithm performs reliably under production-level demands.”

4. Tell me about a time you had to balance multiple priorities under tight time constraints. How did you approach this?

This behavioral question assesses your time management, prioritization, and communication skills in high-pressure situations. The interviewer wants to understand your process in a hectic environment. In your response, be sure to:

  • Provide a specific example of a challenging project with tight deadlines.

  • Explain your thought process for prioritizing deliverables and managing your time.

  • Discuss any tools or frameworks you used to stay organized.

  • Share how you kept stakeholders aligned and set expectations.

  • Emphasize how you delivered high-quality work despite the constraints.


“Last quarter, I was managing 3 concurrent projects with rapidly approaching deadlines. The first was a pricing analysis for a product launch, the second was an attribution model delivery for a large client, and the third was a revenue forecasting presentation for our executive team.

To stay on track, I used a prioritization matrix to map all upcoming deliverables and re-aligned due dates with stakeholders where possible. I also utilized Asana to create dependent task lists and track progress for transparency.

My core focus was completing the attribution model as it was the biggest revenue driver. I shifted other projects where feasible and got support from my team to balance the workload. Through proactive communication, documentation
