Interview tips for this role
- Include a session where the candidate presents their technology vision for your company based on a briefing pack.
- Assess how they talk about people and teams, not just technology. The best CTOs are people leaders first.
- Probe their board communication experience. A CTO who cannot translate tech for executives will struggle.
- Ask how they have handled failure. Genuine leadership experience always includes meaningful setbacks.
Frequently asked questions
What is the difference between a CTO and a VP of Engineering?
A CTO typically focuses on external-facing technology strategy, product direction and innovation. A VP of Engineering focuses on internal engineering operations, team management and delivery. In practice the split varies by company. Smaller companies often combine both roles, while larger organisations separate them.
Should a CTO still write code?
A CTO should maintain enough technical fluency to evaluate architecture decisions and earn engineering respect. However, day-to-day coding usually stops at this level. The most effective CTOs stay connected through architecture reviews, proof-of-concepts and technical mentoring rather than writing production code.
What background makes the best CTO?
Most successful CTOs have 15+ years of progressive engineering experience including hands-on development, technical leadership and organisational management. A strong CTO has typically scaled teams, navigated significant technical challenges and operated at board level. Industry-specific experience helps but adaptability and learning speed matter more.
