1. What is a Data Scientist at Ramp?

At Ramp, the Data Scientist role is far more than just analyzing numbers; it is a strategic function that sits at the intersection of product, engineering, and finance. Ramp is rebuilding the financial stack for modern businesses, and as a Data Scientist here, you are expected to drive the intelligence behind that foundation. You will not simply report on what happened—you will build the frameworks and models that determine what should happen next.

This role is critical because Ramp operates in a high-stakes environment where efficiency and precision are the products. Whether you are working on the Growth team optimizing millions of dollars in marketing spend, or on the Risk team preventing fraud, your work directly impacts the company's bottom line and the financial health of over 50,000 businesses. You will leverage a modern data stack to employ statistical, machine learning, and econometric models that help Ramp scale efficiently.

Expect to work on complex, nebulous problems. You might be asked to discern the causal impact of a campaign on a long B2B enterprise sales cycle or build attribution models that inform future investment. The culture is fast-paced and engineering-driven; you are an essential partner to software engineers and product managers, helping to embed intelligence into the core of the Ramp platform.

2. Getting Ready for Your Interviews

Preparing for a Data Science interview at Ramp requires a shift in mindset. You need to demonstrate not just academic knowledge of statistics, but the ability to apply that knowledge to messy, real-world financial and growth problems.

Key Evaluation Criteria

Statistical Rigor and Causal Inference – Ramp places a heavy emphasis on understanding the "why" behind the data. You must demonstrate a deep understanding of experimental design, hypothesis testing, and causal inference. Interviewers will evaluate your ability to distinguish correlation from causation, especially in complex environments like marketing attribution where data is often imperfect.

Engineering Standards – Unlike some organizations where data scientists work in silos, at Ramp you are part of the engineering ecosystem. You may be interviewed by software engineers (SWEs). Consequently, you are evaluated on your ability to write clean, production-ready Python and SQL. Familiarity with version control, testing, and the software development lifecycle is expected.

Product and Business Sense – You must show that you understand the business context. Ramp cares deeply about ROI and efficiency. You will be evaluated on your ability to translate a vague business question (e.g., "How do we grow faster?") into a concrete analytical framework. Understanding B2B metrics and the enterprise sales cycle is a significant advantage.

Communication and Influence – You will often co-own decisions involving significant capital allocation. Interviewers look for candidates who can explain complex statistical concepts to non-technical stakeholders in Finance or Marketing. Your ability to drive consensus through data is a key leadership trait they assess.

3. Interview Process Overview

The interview process for Data Scientists at Ramp is rigorous and designed to test both your technical depth and your ability to think like a business owner. While the process can move quickly, it is thorough. It typically begins with a recruiter screen to assess your background and interest, followed by a screen with a hiring manager.

The hiring manager screen often digs into your past experience with a focus on impact. Expect questions about specific projects where you used statistical analysis to drive a business result. Following this, successful candidates move to a technical stage. This often involves a live coding or data manipulation challenge, and potentially a "take-home" style case study discussion depending on the specific team.

What makes Ramp’s process distinctive is the cross-functional nature of the panel. You should expect to meet with software engineers in addition to other data scientists. This signals that they value technical implementation skills highly. The final rounds will cover a mix of technical execution, product case studies, and behavioral questions centered on Ramp's values of high velocity and ownership.

The timeline above illustrates the typical flow from application to offer. Note the emphasis on multiple screening layers before the final onsite loop. Use the time between the initial screens and the technical rounds to brush up on your SQL and Python coding speed, as well as your theoretical understanding of A/B testing.

4. Deep Dive into Evaluation Areas

Ramp evaluates candidates across several core competencies. Based on interview data, the following areas are critical for success.

Statistical Analysis & Experimentation

This is the bread and butter of the role, particularly for Growth-focused positions. You need to show you can design experiments that yield valid results even when sample sizes are small or noise is high.

Be ready to go over:

• A/B Testing Design – Calculating sample sizes, selecting metrics, and determining duration.
• Hypothesis Testing – Understanding p-values, confidence intervals, and statistical power.
• Causal Inference – Techniques for measuring impact when a randomized control trial isn't possible (e.g., difference-in-differences, propensity score matching).
• Advanced concepts – Multi-armed bandits, network effects in experimentation, and handling interference between treatment groups.

Example questions or scenarios:

• "How would you design an experiment to test the effectiveness of a new marketing channel where we cannot track individual users perfectly?"
• "Explain how you would handle a situation where an A/B test shows a neutral result but the business intuition suggests a positive impact."

Applied Machine Learning & Modeling

You are expected to build models that solve specific business problems, such as attribution or lead scoring. The focus is less on using the "fanciest" model and more on using the right model.

Be ready to go over:

• Predictive Modeling – Regression (Linear/Logistic), Random Forests, Gradient Boosting.
• Model Evaluation – ROC-AUC, Precision/Recall, RMSE, and choosing the right metric for the business context.
• Attribution Models – Markov chains, Shapley values, and time-decay models specifically for marketing spend.

Example questions or scenarios:

• "How would you build a model to predict which leads are most likely to convert to enterprise customers?"
• "Describe a time you used a statistical model to optimize a budget allocation."

Data Engineering & Coding

Because you collaborate closely with engineering, your code must be efficient and readable.

Be ready to go over:

• SQL Mastery – Complex joins, window functions, and query optimization on platforms like Snowflake or BigQuery.
• Python Proficiency – Data manipulation with pandas and numpy.
• Data Modeling – Understanding schema design and how to structure data for analytics (e.g., dbt models).

Example questions or scenarios:

• "Write a SQL query to calculate the retention rate of users by cohort month."
• "How would you refactor this Python script to make it production-ready?"

5. Key Responsibilities

As a Data Scientist at Ramp, your daily work is a blend of strategic planning and technical execution. You are responsible for defining the analytical frameworks that guide decision-making. For a Growth role, this means you are effectively co-owning the allocation of millions of dollars in marketing spend. You will build the attribution models and investment frameworks that tell the finance and marketing teams where to invest next.

Collaboration is central to the role. You will partner with Martech, Business Systems, and Growth Engineering teams to ensure data is captured correctly across first and third-party sources. You aren't just consuming data; you are influencing the systems that generate it. This involves contributing to the data culture by establishing processes, tools, and best practices for the broader team.

On the technical side, you will employ statistical and econometric models on large datasets to evaluate performance. You will drive the experimental design for new channels, ensuring Ramp can iterate quickly. You will also be expected to "ship" improvements—meaning your models and insights should result in tangible changes to the product or strategy, often requiring you to write production-level code or manage data pipelines.
