What to look for in a great Customer Success Manager

Look beyond friendliness — the best CSMs are commercially disciplined. Ask candidates to walk through how they prioritised their account book when resources were stretched. Strong CSMs can quantify their impact: net revenue retention rates, churn prevented, expansions sourced. Equally important is the ability to hold difficult conversations — probe for a specific example of delivering bad news to a customer and what happened next. Curiosity about the customer's business (not just product usage) usually separates great from average performers.

Where to source Customer Success Manager candidates

Former account managers at SaaS companies are the most obvious pipeline; they already understand recurring revenue models and renewal cycles. Implementation consultants who want to own ongoing relationships are strong candidates who often arrive with deep product and process knowledge. Internal promotions from support teams can work well when the candidate already has product expertise and strong customer empathy. Niche CS communities such as Customer Success Collective host active job boards and talent who self-identify with the discipline.

Interview questions to ask a CSM

Start with 'Tell me about an account you saved from churning — what were the warning signs, and what specifically did you do?' Then explore expansion instincts: 'How do you identify and approach an upsell conversation without it feeling transactional?' Ask how they manage their book when bandwidth is limited: 'If you had 50 accounts and could only deeply engage with 10 this quarter, how would you choose?' Finally, test executive presence by asking them to roleplay a QBR opening with you playing a sceptical VP.
