For other org's out there looking to grow your Eng team I highly recommend trying Triplebyte! As a user I think it's super intuitive with great candidates - also did this case study with them (Zeal <> Triplebyte)
So they hire a special agency which jumps from LinkedIn to GitHub to actually verify their needed tech stack.<p>That's actually a cool business model, because we know that hiring agencies are not able to parse GitHub, and thus are not able to check the needed tech stack.<p>You could also go the easier route, but big companies prefer the slow, expensive ones.
