Speakers

YC alumnus and former partner Harj Taggar and Triplebyte cofounder Ammon Bartram explain how to source, evaluate, and close engineering hires at a Y Combinator talk.

Build the sourcing funnel

Harj frames hiring as sourcing, screening, and closing, then recommends starting with personal networks. Make an exhaustive list of engineers you know, ask them to join, and ask for referrals if they decline. As the team grows, hold sourcing sessions where everyone lists potential candidates.

Choose recruiting channels and timing

Ammon compares marketplaces, LinkedIn and GitHub outreach, job boards, and meetups. He recommends personalized messages over high-volume cold outreach, and distinctive job descriptions that explain the founder’s story and the work. Harj advises making the first engineering hire yourself; consider recruiting help when hiring about one engineer a month for six months or spending over half your time sourcing.

Make interviews more consistent

Ammon says Triplebyte’s interview data showed low interviewer agreement, just over 0.1 on a zero-to-one scale. He recommends deciding which skills matter, using consistent questions and defined scoring criteria, and keeping credentials out of technical assessments. Multi-step questions, several questions per session, and attention to false negatives can improve the signal.

Adapt the process for an early startup

Small teams can use a simple written guide to structure interviews, even when they cannot repeat the same questions for many candidates. When sourcing is difficult, Ammon recommends screening fewer people out before the onsite. For the earliest hires, he says productivity and ownership may matter more than polished code.

Close candidates with speed and clarity

Harj recommends moving quickly, giving candidates a considerate interview experience, and describing company culture with specific trade-offs. Bring teammates and relevant investors into follow-up conversations, and present full compensation details, including salary and equity. To compete with large companies, Ammon suggests discussing responsibility, learning, growth, the distinct opportunity, and mentorship where the team can provide it.

Takeaways

  • Start hiring by asking people you know, then build a repeatable referral habit with your team.
  • Use targeted outreach and track how candidates move through each hiring stage.
  • Define job-relevant skills before interviews, and give interviewers consistent questions and criteria.
  • When candidate supply is thin, avoid rejecting people too early; weigh the cost of false negatives alongside bad hires.
  • Move quickly and explain salary, equity, culture, and the role’s growth opportunities clearly.
