Why European teams choose Yoong

The human-vetted layer above AI screening

AI can screen CVs. It can't run deep L6–L8 interviews or judge attitude and culture fit. Yoong is the human layer that tells you who is genuinely good enough.

De-risked & human-vetted

Interviewers are practising senior engineers, not recruiters with a script. Every candidate maps to one standardized scale — comparable across roles and teams.

Senior talent, Vietnam rates

Access genuinely senior engineers at a fraction of EU market rates — priced by verified level, so you pay for the seniority you actually get.

Ready fast — 14-day shortlist

A qualified shortlist in two weeks. You meet candidates who've already cleared the bar — no long list to filter, speed promised only when an engineer is truly ready.

The problem · why now

The problem isn't a lack of CVs.

It's a trustworthy, fast way to know who's truly good enough — before you spend an offer and three months of onboarding finding out.

>30 days

Open senior seats become an interview-bandwidth bottleneck — slipping roadmaps and overloaded staff engineers.

80%

of employers struggle to hire to their technical bar — the right level is the hard part, not the headcount.

AI CVs

flood the funnel — volume up, trustworthy signal down. Polished applications no longer prove capability.

What we do

Match the service to the pain

From a dedicated long-term engineer to a one-off vetting pass — three services, one human-vetting engine behind all of them.
