What a day looks like in customer success

AM-style days run on calendar — quarterly business reviews, renewal conversations, escalation calls. The interrupt-driven side is responding to customer questions, looping in engineering on bugs, and translating product roadmap into language customers care about. Best CSMs spend half their time understanding the customer's business well enough to make strategic recommendations.

Junior-to-senior progression in customer success

CSM (1-3 years) owns a book of accounts. Senior CSM (3-5) handles strategic accounts. Team lead (5-7) manages a few CSMs. Director (7+) owns the org and renewal targets. Adjacent moves are common: into product (deep customer empathy), into sales (proven retention skill), or into ops (process-building).

What to expect in customer success interviews

Mock customer call: handle an angry customer, run a QBR. Behavioral: walk through a save you owned, a churn you couldn't prevent. Domain knowledge for the specific industry the company sells into. For tech CS roles, basic SQL or product analytics is increasingly required.
