An experiment shows a 3% lift with p=0.08. What conclusions can you draw? What are the caveats?
Analytics questions at Salesforce evaluate your ability to define metrics, design experiments, and derive actionable insights from data. This Take-home Project question tests your end-to-end analytical thinking.
What the Interviewer Expects
- Design complex experimentation strategies for tricky scenarios
- Handle multi-armed bandits, switchback experiments, and quasi-experiments
- Address long-term effects vs short-term metrics
- Propose causal inference methods when randomization is not possible
- Build a measurement framework that connects metrics to business value
- Discuss organizational experimentation culture and maturity
Key Topics to Cover
How to Approach This
- Define success metrics carefully. A good metric is measurable, actionable, and aligned with business goals.
- Run experiments long enough to account for novelty effects and weekly seasonality.
- Use funnel analysis to identify where users drop off for maximum optimization impact.
- Segment results by key dimensions (platform, country, user cohort) to catch hidden patterns.
- Consider network effects and interference between treatment and control groups.
Possible Follow-up Questions
- How would you handle interference between treatment and control?
- How would you handle seasonality in your experiment?
- How would you handle an experiment where the control and treatment groups are different sizes?

Problem Setup
In this experiment, we observe a 3% lift in the conversion rate resulting from a new feature or change, with a p-value of 0.08. The primary analytical question is whether this lift is statistically si...
Methodology
Given that the p-value of 0.08 is above the common significance level of 0.05, we conclude that the lift is not statistically significant at the conventional threshold. However, we can perform a power...
