Intuit’s data science interviews typically begin with an initial phone screen, followed by a technical video interview and a take-home challenge. Candidates who advance past these stages are invited to an onsite interview consisting of four 45-minute rounds with various team members, including data scientists, a technical manager, and a hiring manager.

Initial Screen

The initial screen is a resume-based phone interview with a recruiter or HR partner. This conversation focuses on your background, past projects, and overall fit for the team. Questions are largely resume-driven, with an emphasis on how your prior experience maps to the role and business context.

Technical Screen

The technical screen takes place after the recruiter call and is typically conducted either by an Intuit hiring manager or through Karat, an external interviewing service. Interview questions for data science roles commonly test analytics and coding fundamentals in SQL and Python.

Candidates may be asked open-ended modeling and product questions, such as:

Let’s say you work at a bank that wants to build a model to detect fraud on the platform.

The bank plans to implement a text messaging service that alerts customers when a transaction is flagged as potentially fraudulent, allowing them to approve or deny the transaction via text response.

How would you build this model?

This interview typically lasts about an hour. Interviewers evaluate technical reasoning, clarity of thought, and how well you explain your approach. Time is also reserved to discuss past projects, so candidates should be prepared to speak in depth about their work and its real-world impact.

The Take-Home Challenge

Before the onsite stage, candidates are given a take-home data challenge. Some senior-level candidates report that this assignment involves building a prediction model, designing an A/B test, and analyzing a dataset with approximately 250,000 rows. In addition to the technical work, candidates are expected to prepare a presentation that clearly explains their methodology, assumptions, results, and conclusions.

Applicants are typically asked to complete the take-home within a limited time window, often around four hours.

Some candidates have also reported using the Glider AI platform during portions of the interview process. This tool includes remote proctoring features such as eye movement and facial expression tracking, reinforcing expectations around independent work and adherence to interview guidelines.

The Onsite Interview

The onsite interview at Intuit consists of four interview rounds: two technical interviews, one data challenge presentation, and one behavioral interview. Technical questions are generally open-ended and span statistics and A/B testing, experimental design, modeling, SQL, and machine learning.

A typical onsite structure includes:

• Data challenge presentation: Candidates present their take-home analysis, walking through their modeling approach, experimental design, and insights. Interviewers focus on clarity, structure, and how well candidates connect results to business decisions.
• Technical interview with a technical manager: This round emphasizes prior experience, modeling judgment, and machine learning concepts.
• Technical interview with a data scientist: Candidates are tested on SQL, algorithms, probability, and statistics, often in a conversational format.
• Hiring manager interview: This is a standard behavioral interview. Candidates are encouraged to structure responses using the STAR framework to clearly communicate impact and ownership.

The exact order of these rounds may vary depending on the team and role.

At Interview Query, we love to hear from those who’ve successfully landed jobs in the data science field. To help the rest of our community, we’re sharing their career path stories and approaches to interview preparation.

We caught up with Owen McCarthy, who joined Intuit after completing his Bachelor’s in Data Science at UCSD in 2020 and followed an unconventional path! We discussed his personal journey, tips for getting to the interview stage of applications, and the Intuit interview guide.

What was your journey into data science?

I attended the University of California, San Diego, which didn’t have a data science major when I started. Instead, I blended the computer science and business majors to build a bridge between them and was lucky that they kicked off a dedicated DS program my sophomore year. I was part of the inaugural cohort to graduate from this new program and also snagged a business minor on the way out.

I started looking for data science roles, with a strong focus on natural language processing. OpenAI and GPT-2 were just coming out, and I started looking for data science roles, with a strong focus on natural language processing. OpenAI and GPT-2 were just coming out, and by the time GPT-3 launched, I knew that this was a field worth putting a real bet on career-wise. The roles that companies were hiring for wanted more extensive educational backgrounds than mine, but I got lucky with a data science program with a company called Barisk.

The program was designed as a rotational, where every 18 months, you would be moved to a new business sector and geographic area. After three rotations, or three and a half years, you come out as a senior data scientist, a project manager, or a data science manager.

Even though it was still geared towards master’s graduates, I noticed a small input at the bottom of the application, which allowed you to communicate extra information to the hiring managers. In this way, I overcame the lack of a higher degree by speaking with the team more directly about my interest in the field.

How did you land an interview with Intuit?

I did not go through the regular channels to get the interview. I paid for LinkedIn Premium, searched for data science recruiters, and emailed them directly if they had an email in their bio. You can also try to look up their email on the web if you know their name and company. There are quite a few websites for that.

I would email these individuals, letting them know that I was interested in their group and that I had experience as a data scientist. I also made sure to attach my resume and saw quite a bit of success with this method.

Intuit eventually got back to me on a senior data science position, and I started preparing for my interview there!

How did you prepare for the interview?

Preparing for data science interviews can be tricky since there’s so much breadth of content. You’re being tested on Python or R knowledge, SQL, small data structures, stats and probability, machine learning, and some business or product questions. There is just so much out there to know.

For the current role, I studied SQL for my interviews since that’s what they advertised and were looking for in the job listing. I also reviewed a lot of the theory behind general machine learning algorithms. Some examples are:

• How does a neural network generally work?
• What’s the difference between different neural network architectures (RNN, CNN, Transformer, etc.)?
• How does SVM (Support Vector Machines) work?
• What’s a linear regression model?
• What’s the difference between boosting and bagging?

Knowing these foundational machine learning concepts proved to be really helpful.

Lastly, my big tip would be to practice Python and SQL. While it’s essential, don’t overlook the importance of preparing for behavioral interviews. I observed with my data science colleagues that they typically ace the technical portions but will get leveled if their behavioral answers aren’t strong. Always use the STAR method (situation, task, action, and result), be thoughtful, and answer the prompt.

What was your experience interviewing at Intuit?

Recruiter Call (30 Minutes)

This was your regular thirty-minute call to determine what roles I was qualified for and if I could work from the Mountain View campus or remotely. We also discussed salary and benefits for certain roles, which I stayed non-committal on, pending the final position and scope.

Technical Screening (1 Hour)

I had one Python question and two SQL questions, which took around 30 to 40 minutes to complete.

There was then around 20 minutes to discuss my background.

If there is extra time, they’ll likely ask some filler questions on Python or general machine learning, as well as basic topics like bias, variance, trade-off, boosting, or bagging.

The Four Round Interviews (3-4 Days)

Round 1: Solution Creation and Demonstration

You are given a problem and need to create a machine-learning solution to demonstrate and present. That presentation is to the team and needs to be around an hour in length. That’s a lot of time to speak to this solution, so you need to do quite a bit of prep for it. They also spent around ten minutes on the candidate’s background as a chance to get to know you better.

Round 2: Skip-Level Manager (The Boss’ Boss)

This interview is with your supervisor’s manager and is all about stakeholder management. They want to know how you go about product-related projects, how you work with others, your formal or informal leadership style, and what type of manager you’re looking for. There might also be a few business questions peppered in here.

Round 3: Technical Interview

Another hour-long technical assessment, again focused on conversational-style questions, Python, SQL, and your background again.

Round 4: Hiring Manager

This is just a typical behavioral interview, with nothing too unexpected. Don’t forget your preparation and the simple STAR framework.

Note: The exact order of the final four interviews may be different for each candidate.

Modeling and Machine Learning

1. How does boosting work?

   This question evaluates your understanding of ensemble learning methods. Interviewers want to see whether you can explain how boosting combines weak learners sequentially, focuses on previously misclassified examples, and improves overall model performance.

2. What are the limitations of linear regression?

   This question checks your understanding of core modeling assumptions. Strong answers discuss issues such as linearity, sensitivity to outliers, multicollinearity, and situations where linear regression fails to capture complex patterns.

3. Describe how a random forest works under the hood.

   This question evaluates conceptual depth in tree-based ensembles. Interviewers expect you to explain bootstrapping, feature randomness, and how predictions from individual trees are aggregated.

4. What features would you add to a model that doesn’t already exist?

   This question assesses feature engineering judgment. Strong answers show how you reason from problem context, available data, and user behavior to propose features that could improve performance.

5. If there was a feature that 100% of the users used, would it be a good feature?

   Interviewers use this question to probe understanding of predictive signal. Candidates should recognize that features without variance often provide little information gain.

6. What’s an adequate rebalance of an imbalanced dataset?

   This question evaluates your understanding of class imbalance and modeling tradeoffs. Interviewers look for discussion of resampling strategies, class weighting, and metric selection rather than a single fixed ratio.

7. How would you combat overfitting when building tree-based models?

   This question tests practical knowledge of generalization techniques. Strong answers cover methods such as limiting tree depth, setting minimum samples per leaf, and using ensembles effectively.

Statistics and Probability

1. Let’s say you can play a coin-flipping guessing game either once or 2 out of 3 games. What is the best strategy for winning?

   This question tests probability intuition and decision-making under uncertainty. Interviewers expect a clear comparison of expected outcomes and a logically justified strategy.

Algorithms and Coding

1. Given a long array that you can’t store, how do you find the median?

   Interviewers use this question to assess algorithmic thinking under memory constraints. They look for approaches such as streaming algorithms or approximation techniques.

2. Implement an iterator function that takes three iterators as the input and sorts them.

   This question tests hands-on programming and problem-solving skills. Interviewers focus on how you reason about iteration, ordering, and efficiency, not just correctness.

Data, Experimentation, and Senior-Level Scope

1. Build a prediction model using a large dataset and explain your evaluation approach

   This question assesses your ability to develop a predictive model at scale and justify your decisions. Interviewers look for clear reasoning around feature selection, data splitting, evaluation metrics, and balancing performance with interpretability on datasets with hundreds of thousands of rows.

2. Design an A/B test to evaluate the impact of a predictive model

   This question tests your understanding of experimental design in a real product setting. Candidates are expected to define hypotheses, select success metrics, structure control and treatment groups, and analyze results to support a decision.

3. Analyze a large dataset and identify insights worth presenting to stakeholders

   Interviewers use this question to evaluate prioritization under scale. Strong answers focus on narrowing the problem, identifying high-impact signals, and translating analysis into decision-ready insights.

4. Prepare and present the results of a modeling and experimentation assignment

   This question assesses your ability to communicate technical work effectively. Interviewers pay close attention to structure, clarity, explanation of assumptions and tradeoffs, and how results connect to business outcomes.

Behavioral and Ownership

1. Tell me about a time when you exceeded expectations during a project. What did you do, and how did you accomplish it?

   This behavioral question evaluates ownership, initiative, and impact. Interviewers look for clear narratives with concrete actions and measurable results.
