To interview a Customer Success Manager, test how they drive adoption, prevent churn, and grow accounts while keeping customers genuinely successful. This set covers craft questions on onboarding, health scoring, renewals, and expansion, plus behavioral and situational prompts that reveal how they handle at-risk accounts and difficult customers.
Probe the balance every CSM walks: advocating for the customer while protecting revenue. Use real account scenarios, an angry renewal, a silent low-adopter, to see whether they're proactive or merely reactive.
How do you run a customer's first 90 days so they reach value, not just get set up?
What to look for: A structured onboarding tied to the customer's goals and a defined time-to-value, not just feature training or a kickoff call.
How do you build and use a customer health score to catch risk early?
What to look for: Mixing usage, engagement, sentiment, and business outcomes, leading indicators over lagging, and acting on the score not just tracking it.
A key account's usage has been quietly declining for a month. How do you respond?
What to look for: Proactive outreach, diagnosing whether it's adoption, fit, or a champion change, and a plan to re-engage before it becomes a churn.
How do you handle a renewal where the customer is questioning the value they've received?
What to look for: Leading with outcomes and ROI delivered, revisiting goals, addressing gaps honestly, and not defaulting to a discount to save it.
How do you identify and pursue expansion without being pushy or damaging trust?
What to look for: Tying upsell to the customer's success and unmet needs, timing around value moments, and earning the right to expand by delivering first.
How do you balance advocating for the customer internally with protecting the company's revenue?
What to look for: Genuine customer empathy, but business judgment about what's reasonable, and influencing product/support without overpromising.
How do you segment your book of accounts and decide where to spend your time?
What to look for: Prioritizing by revenue, risk, and growth potential, a scalable cadence (high-touch vs tech-touch), and not just servicing whoever shouts loudest.
What signals tell you a customer will churn before they say so, and what do you do?
What to look for: Early warning signs (low adoption, champion turnover, silence, support spikes) and a concrete save play, not reacting only at cancellation.
Tell me about an account you saved from churning. What was the turning point?
What to look for: A proactive diagnosis, a concrete plan, internal coordination, and a measurable outcome they drove.
Describe a time you had to deliver bad news to a customer, like a missing feature or a price change.
What to look for: Honesty, empathy, framing around the customer's goals, and preserving the relationship through a hard message.
Tell me about a time you advocated internally for a customer and what happened.
What to look for: Effective cross-functional influence, balancing one customer against the broader business, and following through.
An angry customer threatens to cancel over a bug your team can't fix immediately. How do you handle the call?
What to look for: De-escalation, honesty about timelines, owning the relationship, and a plan that rebuilds trust rather than empty reassurance.
Your largest account is happy but barely using the product. How do you protect that renewal?
What to look for: Recognizing that satisfaction without adoption is fragile, driving real usage and value, and not coasting on a good relationship.
A customer asks for a feature on your roadmap but wants it now. How do you manage expectations?
What to look for: Honesty about timelines, finding interim workarounds, channeling feedback to product, and not overpromising to keep them happy.
