freshworks Data Scientist Interview: Questions, Experience & Prep (2026)

Freshworks builds customer engagement software used by businesses worldwide, with flagship products like Freshdesk (customer support), Freshsales (CRM), and Freddy AI (their embedded AI assistant layer). Data Scientists here work on problems like predicting customer churn, building lead-scoring models, and improving AI features inside their SaaS products.

As of July 2026, knok's job radar shows 145 open Data Scientist roles at Freshworks, making it one of the more active SaaS hirers for this role in India. The interview process typically runs across multiple rounds covering SQL, machine learning fundamentals, product thinking, and past project experience. Candidates report a strong emphasis on business impact: Freshworks interviewers want to see that you connect your analysis to product or revenue outcomes, not just model performance numbers.

Based on candidate reports and the nature of Freshworks' SaaS products, these questions come up most often:

1. How would you define and measure customer churn at a SaaS company like Freshworks?
2. Write a SQL query to find customers who raised no support tickets in a given period but showed high product usage.
3. How would you build a lead-scoring model for Freshworks CRM? Walk me through the features, model choice, and how you would evaluate it.
4. Describe how you would design an A/B test for a new feature in Freshdesk. What metric would you use as your primary success metric?
5. Freshworks Freddy AI is embedded across its products. How would you evaluate whether an AI feature is actually improving user outcomes vs. just being used more often?
6. How would you handle class imbalance when predicting which customers are likely to churn?
7. A product manager asks: 'Why did ticket resolution times increase this quarter?' Walk me through your analysis approach step by step.
8. How would you prioritize which customer signals to include in an upsell propensity model when you have hundreds of potential features?
9. Explain precision and recall to a sales team that has never studied statistics. Give a concrete example using a sales context.
10. Describe a time your analysis directly changed a product or business decision. What would you do differently now?
11. How would you detect anomalies in support ticket volume across Freshworks customers? What would trigger an alert?
12. Two A/B test variants show no statistically significant difference after the planned run. What do you recommend to the product team, and why?

Use these as a starting point and replace the details with your own experience.

Q: Describe a time your analysis directly changed a product or business decision.

*Situation:* At my previous company, the customer success team was seeing a spike in repeat support contacts from a specific customer segment, and retention in that group was declining.

*Task:* I was asked to identify why these customers were reaching out repeatedly and whether there was a pattern we could act on.

*Action:* I joined support ticket data with product usage logs and found that customers who used two specific features together were hitting a silent failure state the product team had not tracked. I built a simple flag to identify at-risk accounts, quantified the affected segment, and presented the finding to the product and customer success teams with a prioritized list of accounts to contact.

*Result:* The product team shipped a targeted fix in the next sprint. Customer success proactively reached out to flagged accounts. Repeat contacts from this segment fell noticeably in the following quarter. I was careful to note that other changes happened at the same time, so we could not attribute all the improvement to the fix alone.

Q: Tell me about a time you had to explain a complex model to a non-technical stakeholder.

*Situation:* I had built a churn prediction model using gradient boosting, and the sales leadership team wanted to use the output to prioritize which accounts to call. But they did not trust a 'black box score.'

*Task:* I needed to explain the model in a way that made them confident enough to act on it, without oversimplifying the nuance.

*Action:* I dropped the technical language and reframed the model output as 'these are the accounts that look most like customers who left us in the past.' I used SHAP values to show the top three reasons any given account was flagged (low login frequency, recent support tickets, no expansion activity) and presented it as a one-page summary alongside the score list.

*Result:* The sales team adopted the model output in their weekly account review. They started using the reasons column to tailor their outreach, which they said felt far more actionable than a raw score.

Q: Describe a project where you worked with messy or incomplete data.

*Situation:* I was building a feature usage model and discovered that the event-logging pipeline had gaps: some product events were not being captured consistently across mobile and web clients.

*Task:* I had to decide whether to wait for clean data, work around the gaps, or flag the limitation and proceed with caveats.

*Action:* I audited the missing data patterns and found the gaps were not random. Mobile sessions were under-reported by a consistent factor. I documented this, imputed session counts for mobile using a ratio derived from periods where both sources were available, and clearly flagged the imputation in my analysis. I also filed a ticket with the data engineering team to fix the upstream pipeline.

*Result:* The model shipped on schedule with documented caveats. When the pipeline fix landed and I re-ran the model on clean data, the results were consistent with my imputed version, which validated the approach.

For SQL questions: Clarify the business question before writing a single line. State your assumptions out loud (for example, what counts as 'active,' what is the grain of the table). Write the query in steps: filter first, aggregate second, layer on window functions if needed. Read back your result set and check whether it actually answers the question asked.

For ML design questions: Follow a structured flow. Start with the business goal and the success metric. Then move to data sources and features. Then choose a model family and justify it (simpler is often better for SaaS problems where interpretability matters). Finish with evaluation: how will you know the model is working in production, not just on a held-out test set.

For 'why did metric X change' questions: Use a top-down breakdown. Decompose the metric into its components (for example, average resolution time = total handling time divided by tickets resolved). Check whether the change is in the numerator or denominator, and whether it is concentrated in a segment, region, or time period. List hypotheses and say how you would test each one.

For A/B test questions: Cover four pillars: the hypothesis and primary metric, how you would size the experiment (mention statistical power without inventing specific numbers), the duration and guardrails, and what you would do if results are inconclusive or if guardrail metrics move in the wrong direction.

For behavioral questions: Use STAR (Situation, Task, Action, Result). Keep Situation and Task brief. Spend most of your time on Action (what you specifically did, not 'we') and Result (a business outcome, not just a technical metric).

Freshworks interviewers, based on candidate reports, look for a few things that go beyond textbook ML knowledge.

Business impact first. Freshworks is a product company. Interviewers want to hear about the business problem before the model. If your answer starts with 'I chose XGBoost because...' without first explaining what you were trying to achieve, you will lose points.

Comfort with SaaS metrics. Know what churn rate, net revenue retention, CSAT, and ticket resolution time mean and how they relate to each other. Freddy AI features are a recurring topic: be ready to discuss how you would measure the value of an AI assistant embedded in a support or sales product.

Clear communication. Freshworks serves a wide range of business customers, and Data Scientists here regularly present to non-technical stakeholders. Practice explaining your work in plain language. Avoid jargon unless the interviewer introduces it first.

Practical ML judgment. Interviewers typically prefer candidates who can say 'logistic regression is the right starting point here because the problem is binary, the data volume is moderate, and the sales team needs to understand the inputs' over candidates who default to the most complex model available.

Intellectual honesty. If you do not know something, say so and reason through it out loud. Freshworks interviewers report valuing candidates who acknowledge data limitations, flag assumptions, and say 'I would validate this by...' rather than presenting overconfident answers.

Week 1: SQL and data manipulation. Practice window functions (RANK, LAG, LEAD, running totals), multi-table joins, and CTEs. Focus on SaaS-style questions: customer activity tables, support ticket logs, subscription events. For each query you write, read back the result set and verify it answers the business question, not just that it runs.

Week 2: Machine learning fundamentals. Revisit classification metrics (precision, recall, F1, AUC-ROC) and be able to explain the trade-offs in plain language. Practice framing imbalanced classification problems. Churn prediction is a classic Freshworks example. Revise tree-based models and know when simpler alternatives make more sense.

Week 3: Product sense and SaaS context. Read up on how Freshdesk, Freshsales, and Freddy AI work. Practice metric decomposition: pick a SaaS metric, break it into components, and walk through how you would diagnose a drop. Prepare two or three examples of how AI or ML has been embedded in SaaS products and what the measurement challenges are.

Week 4: Behavioral prep and mock runs. Write out STAR answers for the top behavioral questions listed above. Practice saying them out loud, not just writing them. Time yourself: aim for two to three minutes per answer. Do at least one mock interview where you talk through an SQL or ML question end-to-end with someone listening.

Jumping to the model before the problem. When asked to 'build a churn model,' many candidates immediately list features and algorithms. Interviewers want you to start by asking: what decision will this model inform? Who will act on it, and how? Answering those questions first changes everything about how you design the model.

Skipping assumptions in SQL questions. Freshworks SQL questions often have deliberate ambiguity (what counts as a 'churned' customer? what is the grain of the table?). Candidates who write code without clarifying assumptions often produce technically correct queries that answer the wrong question.

Reporting model accuracy without business context. Saying 'my model achieved high accuracy' in a churn context is a red flag if you do not explain the class distribution. An accuracy-focused framing suggests you have not thought about the cost of false negatives (missing a customer about to leave) vs. false positives (wasting a customer success call on someone who was going to renew anyway).

Over-engineering the solution. Proposing a deep learning model for a problem with a small structured dataset signals poor judgment. Freshworks interviewers value candidates who match solution complexity to actual problem constraints.

Treating A/B tests as binary pass/fail. Many candidates say 'if the p-value is below 0.05, we ship it.' Interviewers expect you to discuss sample ratio mismatch, novelty effects, appropriate experiment duration, and what guardrail metrics you would watch.

Not asking clarifying questions. Freshworks interviews are collaborative. Jumping straight into an answer without clarifying the scope, the audience, or the constraints makes you look less like a working Data Scientist and more like someone rehearsing prepared answers.
