The Problem

Technical interviews no longer
predict job performance.

The way engineers code has far outgrown the way companies hire. Use a process that actually tests how good engineers are at shipping.

01

Engineers use AI daily, but interviews ban it

Every engineer ships with AI, and your interview should reflect that.

02

Vetting candidates takes up valuable time

Engineers want to spend time building, not double checking a take-home for AI slop.

03

Take-homes are unstructured and unscalable

No standardization, no visibility into process, no way to compare candidates fairly.

04

Work trials are the gold standard, but don’t scale

The best signal is watching someone do the work. Saffron makes that possible for every candidate.

The Platform

See exactly how every candidate builds.

01 — Create Assessment

Connect your repo. Define your rubric. Send a link.

Link your GitHub repo or choose from pre-built templates. Then define custom evaluation criteria with 10+ AI review agents. Invite candidates with a single link.

02 — Candidate Experience

Candidates build on your actual codebase

Candidates get a browser-based IDE with Claude Code on your actual repo — no local setup required. They build, debug, and refactor real code, exactly how they'd work on the job.

03 — Review Results

Know exactly how they built it

Multiple AI agents score every submission against your criteria. See which code was human-written vs AI-generated, replay the full session, and verify understanding through AI-checked debrief questions.

Compare

Side by side, it's not close.

What interviews tell you

“They solved the algorithm.”

What Saffron shows you

They architected a real feature on your codebase, iterated 3 times, used AI for boilerplate while writing core logic by hand.

What interviews tell you

“We don’t know how they used AI because we banned it.”

What Saffron shows you

Every prompt, every AI suggestion accepted or rejected, every iteration — captured and scored.

What interviews tell you

“The panel gave mixed feedback.”

What Saffron shows you

10+ independent agents scored against your criteria, with evidence cited for every rating.
