Role overview
A Customer Success Manager (CSM) owns post-sale outcomes: onboarding, adoption, retention, and expansion. The role is part account management, part product expert, part project manager.
The biggest screening trap is mistaking a support-leaning CSM for a commercial CSM. Decide which one your business needs before you read the first resume.
Job criteria
- 2–5 years in CSM, account management, or implementation roles
- Quantified retention or NRR (Net Revenue Retention) track record where applicable
- Comfort being the technical face of the product to customers
- Experience with QBRs (Quarterly Business Reviews), success plans, and renewal motions
- Strong written communication — most of the job is written follow-up
- Tooling: at least one of Gainsight, ChurnZero, Catalyst, Vitally, HubSpot
What to screen for
- Retention numbers. "Managed a $4M book at 112% NRR" is real. "Drove customer satisfaction" is not.
- Proactive vs reactive pattern. Does the resume describe success plans, QBRs, expansion playbooks — or just ticket triage?
- Technical depth. The best CSMs can demo. Look for product certifications, internal training, hands-on tooling.
- Account complexity. A CSM with 200 accounts at $5k each is a different hire from one with 8 accounts at $200k.
- Renewal accountability. Was the candidate measured on renewal and expansion, or just NPS?
Red flags
- Resume reads as a support engineer with a CSM title
- No quantified retention or expansion outcomes
- "Customer-obsessed" language without examples of pushing back on a customer when needed
- Job-hopping every 12 months with no story
- Heavy reliance on the support team to "handle the technical stuff"

Interview questions
- Walk me through a renewal you saved. What was at risk, and what specifically did you do?
- Tell me about a customer you fired or recommended firing. Why?
- How do you structure a QBR? What is the agenda for one with a struggling account?
- Describe your approach to expansion. How do you spot it without becoming a salesperson?
- A customer is escalating about a product gap that is not on the roadmap. What do you do in week one of that situation?
- What is the most technical thing you can demo today without help?
