How 9fin cut time-to-hire by 58%
Series B FinTech 9fin doubled their engineering team in just 4 months last year, slicing their time-to-hire down from 64 to 27 days.
Along with thorough headcount planning and providing interview training for the entire engineering team to create alignment and reduce bottlenecks, they reimagined technical assessment with two key approaches:
💬 Structured case studies
"We've found case studies to be the most effective performance measure when technically assessing candidates."
Rather than relying on CVs alone, 9fin uses role-specific case studies that replicate real tasks across Engineering, Product, Marketing, and Design. These assessments are tied to clearly defined competencies, giving both sides a more meaningful sense of fit.
Talent Director, Alice Simpson explains how 9fin reframes the time investment as mutual value:
“It’s part of the ‘give and get’ of hiring and interviewing. Candidates get to experience the types of challenges they’d face in the role, so they can assess whether the work excites and stretches them.”
To make case studies fair and effective:
🎥 Coderbyte for recorded pair programming
For software engineering roles, 9fin implements Coderbyte for recorded pair programming assessments. Candidates demonstrate their skills in real-time while giving engineering reviewers the flexibility to evaluate recordings at 1.5x speed. This not only saves time but improves consistency across the evaluation process, without compromising on quality.
