A sample answer to question 1

What differentiates a Senior Customer Success Manager from a Customer Success Manager?

The core skills are the same, but the scale, complexity and influence are greater. I'd expect to manage the most strategic or complex accounts, where there are multiple stakeholders, executive relationships and larger revenue at stake, and to be accountable for outcomes such as net revenue retention and expansion, not just activity. I'd operate at senior level in the customer, building relationships with directors and C-suite, running executive business reviews and linking our product to their strategic goals. Internally I'd influence product, sales and support, bring customer insight to roadmap discussions and manage escalations across teams. I'd also mentor less experienced CSMs, help refine playbooks and onboarding, and contribute to the team's strategy. So it's less about doing the standard process well, and more about shaping the process, handling ambiguity and raising the standard for everybody around me.

Common mistake to avoid: Saying the only difference is larger accounts; ignoring mentoring
