By Sade Clarke, Senior Lead, Sales Stream at Jumpstart. Updated September 2026.Most sales interviews at startups now include a case study: pitch us a product, run a mock discovery call, or handle an objection live. Here's how to approach it well.
Start with the brief, not the deck. Founders would rather see you ask two sharp clarifying questions about the persona and the problem than open with fifteen slides. It shows you'd actually run discovery properly on a real call.
Structure your pitch around a problem, not a feature list. What is this buyer's day like without the product, what does it cost them, and how does what you're selling change that. If you can tie it to a metric, even a rough one, do it.
Practise the objection-handling section out loud, not just in your head. The candidates who stumble aren't the ones with weaker answers, they're the ones hearing the objection for the first time mid-sentence.
End with a close, always. Even in a mock scenario, ask for the next step. Founders are watching for this specifically, plenty of good pitches never actually ask for the business.
