First Critical Hire Interview Guide

Tell us about the role. We'll build your interview guide.

For example, when hiring a Head of Engineering, a tailored question might be: ‘Describe a time when you had to balance technical debt with new feature development.’ The scoring guide specifies that a strong response demonstrates task prioritization based on business needs and effective stakeholder communication.

Context that matters.: Role, level, industry, company background, and key challenges. Each question is designed to ensure your interview guide is both comprehensive and focused.
Adaptive depth.: Hiring a junior developer at a Series A requires different questions than hiring a CTO at pre-seed. Standards are adjusted to fit your specific situation.
Ready to use.: Ready to print and bring into the room before your next call. Not a rough draft. A working interview guide .

Structured Interviews

This interview process has helped build top-performing teams.

Companies like Google and Stripe achieve better hiring outcomes by using consistent questions, scoring, and standards for every candidate. You can now implement the same approach.

Everything you need, nothing you do not.: Each interview round has a clear purpose, with questions tailored to your specific role rather than generic templates. Follow-up questions are available to explore responses in greater depth.
Objective evaluation.: Scoring levels (Exceeds / Meets / Below) include specific behavioral descriptions for each competency. No more debating what "good" means. Turn "I liked them" into documented evidence you can share with your team and support.
Identify potential issues before they lead to costly mistakes.: Your interview guide includes warning signs identified by experienced hiring managers, enabling you to detect misaligned motivations, hidden expectations, and subtle indicators of possible problems from the outset.
