What "vetted" actually means
Vetting is a sequence of independent checks, not a single screening call. A serious partner will publish what each step measures and who runs it. The strongest pipelines include: a recruiter-led screen for English fluency and motivation, a paid technical exercise (live or take-home), a senior-engineer pair-programming session, and a final culture/soft-skills round before the candidate enters the bench.
The training pipeline
A vetting process catches what a candidate already knows. A training pipeline keeps them current. Ask whether the vendor reimburses certifications, runs internal study groups, or pairs engineers with senior mentors. Vendors that skip this end up with engineers who were top-quartile in 2022 but average in 2026.
How HighCircl's stance differs from Toptal/Andela
Toptal and Andela treat the bench as a marketplace — once a developer is on it, they are largely on their own. HighCircl runs a smaller, EU-focused network where vetting and onboarding into client teams is hands-on, with a partner sitting in on the first month of pairings to flag fit issues before they become attrition.
Retention data
Retention is the lagging indicator that tells you whether vetting worked. Industry benchmarks for nearshore engagements sit around 80–85% one-year retention; below that, you are paying for a vetting process that does not predict fit.
How to evaluate a vendor's vetting claims
Ask three questions: (1) Who runs each interview round and what is their seniority? (2) What is the acceptance rate from screen to bench? (3) How many of your last 20 placements are still on the same engagement 12 months later? Vendors that decline to answer these in writing are signaling that the claims do not hold up.
