Onboarding and adoption
Effective onboarding starts with the customer's goals: what outcome did they buy the product for, how will they measure it, and who are the key users? Agree a plan with milestones, get to a first meaningful result quickly, and train the people who'll use the product daily. Adoption grows when you connect features to the customer's goals, share usage data and best practices from similar customers, and find champions inside the account.
Churn risk and health scores
| Signal | Why it matters |
|---|---|
| Falling usage or active users | Value isn't being realised |
| Champion leaves | Loss of internal advocacy |
| Rising support tickets or escalations | Frustration building |
| No executive engagement | Weak strategic alignment at renewal time |
| Late payments or budget cuts | Commercial pressure |
| Low survey scores | Explicit dissatisfaction |
A health score combines such signals with weights validated against past churn, so it predicts rather than just describes. To save an at-risk account: understand the real cause, involve the right stakeholders on both sides, agree a recovery plan with clear milestones, and follow through visibly.
Retention metrics
- Gross revenue retention: revenue kept from existing customers, excluding expansion — capped at 100%.
- Net revenue retention: including expansion, minus churn and downgrades — above 100% means existing customers grow overall.
- Logo retention: share of customers renewing, regardless of size.
- Time to value: how quickly new customers reach their first meaningful outcome.
Difficult conversations
For the angry-customer role play: listen without interrupting, acknowledge the impact, avoid blaming colleagues, state what you can and can't commit to, propose concrete next steps and a follow-up time — then actually follow up. Interviewers watch for empathy, honesty and ownership. Never promise roadmap items you don't control.
Prioritising a book of business
Segment accounts by revenue, growth potential and risk. Give high-value or high-risk accounts proactive, personal attention; serve smaller accounts with scaled programmes such as webinars, automated check-ins and resources. Review health weekly and adjust. See sales interview questions for the commercial side of expansion.
Running a quarterly business review
A good QBR is about the customer's goals, not your product's features. Open with the outcomes they wanted and the progress against them, show usage trends and value delivered in their terms, raise risks honestly, agree priorities for the next quarter, and introduce relevant capabilities only where they serve those priorities. Send a short written summary afterwards. Interviewers may ask you to outline one for a sample account.
Practising
Interviewers follow up on the most specific thing you say, so rehearse the second question as well as the first. CoPilot Interview, a free AI interview assistant, runs customer success mock interviews with follow-ups and produces a report of likely next-round questions. Prepare one save story and one expansion story with the numbers behind them. See also customer service interview questions.

What is net revenue retention?
The percentage of revenue retained from existing customers over a period, including expansion and subtracting churn and downgrades. Above 100% means existing customers are growing overall.
