Sample interview questions
How do you identify and prioritize upsell or cross-sell opportunities within an existing customer portfolio?

I start with account health, product adoption, business goals, and stakeholder feedback. I prioritize opportunities where an additional capability solves a documented customer need, then align with the Account Manager on the value case, timing, and next steps.

Describe how you would manage a complex customer escalation involving several internal teams.

I would establish the impact, urgency, owners, and a single communication cadence immediately. I would keep the customer informed with transparent updates, coordinate internal actions against a recovery plan, and complete a post-resolution review to prevent recurrence.

What metrics would you use to assess the health of a B2B SaaS customer account?

I would combine quantitative and qualitative signals, including product usage, adoption of key features, support trends, renewal status, stakeholder engagement, satisfaction feedback, business outcomes, and expansion potential. The specific weighting should reflect the customer segment and product lifecycle.

How would you work with an Account Manager after identifying a qualified expansion opportunity?

I would share the customer context, pain points, desired outcomes, relevant stakeholders, and evidence supporting the opportunity. We would agree on roles for discovery, solution positioning, and follow-up so the handoff feels seamless to the customer.

How do you communicate customer feedback to product and service teams effectively?

I translate feedback into a clear problem statement with customer impact, frequency, affected workflows, and supporting examples. I distinguish urgent defects from feature requests, close the loop with the customer, and provide internal teams with enough context to make informed prioritization decisions.
