FAQ
Hiring with OpenSource, answered
How does OpenSource screen candidates?
Every candidate is technically assessed by us — people who have written production code — before you interview them. We use realistic work samples and structured, rubric-scored evaluation rather than abstract puzzles, so your interview time goes on people who can genuinely do the job.
How quickly can you deliver a shortlist?
For most roles we come back with a technically screened shortlist within days, not weeks, because we screen candidates ourselves and maintain an active network of pre-vetted engineers, product and data talent.
What does it cost to hire through OpenSource?
We offer three models: contingent (pay only on a successful placement), embedded / RPO (a dedicated recruiter for hiring at volume) and retained search (for senior and business-critical roles). We recommend the right fit for your stage — see our recruitment models guide.
Which locations do you hire across?
We hire for startups and scale-ups across the UK, Europe and the US, with particular depth in London, Berlin, Amsterdam and New York, plus fully remote and hybrid teams.
