A sample answer to question 1

What does a typical week as a Customer Success Executive involve, and how is it different from customer support?

Support reacts to problems, whereas customer success works proactively to make sure clients achieve the outcomes they bought the product for. In a typical week I would hold onboarding calls with new accounts, run quarterly business reviews with established ones, and check health scores to see who needs attention. I would review usage data in a tool like Gainsight, HubSpot or Salesforce, then reach out to customers whose logins have dropped. I would also prepare renewal forecasts, flag expansion opportunities to the account executive and pass product feedback to the product team. Some time goes on escalations, where I coordinate with support and engineering. The measure of my work is retention, net revenue retention and customer satisfaction, so I plan my week around the accounts with the greatest renewal risk or growth potential.

Common mistake to avoid: Describing it as just answering queries; Forgetting the commercial targets
