About customer success / support roles
Customer success owns the post-sale relationship — renewals, expansion, troubleshooting. Support handles inbound tickets. Both can be career-launchers into PM, sales, or ops.
Typical skills: Empathy + writing under pressure, one or more help-desk tools (Zendesk, Intercom), basic SQL is a bonus
Salary insights (US, rough)
Typical range for customer success / support roles in the US is $40,000–$140,000/year, varying widely with seniority, company stage, and city.

How to prep for the interview
CS / support interviews focus heavily on writing and empathy under pressure. Common formats: a take-home where you're asked to respond to 3–4 sample customer tickets (each a different tone — angry, confused, technical), a role-play on a difficult call, and a "how would you handle a customer threatening to churn" scenario.
Prepare to answer: "Tell me about the toughest customer you ever helped", "How do you decide when to escalate vs. handle yourself?", and "What's your process for documenting recurring issues so engineering can fix the root cause?" Strong CS candidates show systems-thinking — every ticket is data about a product problem.
Where this role typically leads
CS / support paths: Support Rep → Senior Support → Support Lead → Manager for ticket-based roles; CS Associate → CSM → Senior CSM → CS Lead → Director of CS for relationship-based roles. CS is a great launching pad for product management, sales, or operations — many CSMs jump after 2–3 years.
The biggest career investment in CS: learning SQL and basic data analysis. CSMs who can run their own retention / expansion analyses (instead of waiting for data teams) become significantly more valuable. For support roles, learning to write good internal documentation (so the same issue doesn't come in 50 times) is the skill that gets you promoted.
Red flags to watch for
- CSM responsible for 100+ accounts. No human can manage that many customers meaningfully. The role will become reactive ticket-clearing, not actual success work.
- Quotas tied to upsell only, not retention. Pushes you to behave like sales, which damages customer trust.
- "Customer obsessed" without mention of training time. The product is probably complex enough that you'll need weeks to learn it — make sure the company invests in onboarding.
- No clear escalation path to engineering or product. You'll get blamed for product bugs you can't fix.
