How to actually get hired at Horizon3
Why applying the normal way doesn't work
Horizon3 runs an applicant tracking system (Ashby), but hiring managers still work referrals first. A cold application to Horizon3 isn't dead, it's just fourth in line behind internal referrals, sourced candidates and recruiter pipelines.
Who to contact at Horizon3
No verified contact route for Horizon3 yet. Expect the hiring manager for the team that's hiring to make the call, but treat this as a model, not confirmed data.
What Horizon3 screens for
relevant experience and ability to operate autonomously
Customize your CV for the Horizon3 role. Matching the job description language helps clear ATS filters.
Mistakes that kill Horizon3 applications
Don't send the same CV you sent everywhere else. Whoever reads applications at Horizon3 can tell, and it's the fastest rejection there is.
Don't open with what you want. Open with what Horizon3 is dealing with right now — is growing, and what you'd do about it.
The wait-and-hope strategy fails. Follow up on day five — response rates roughly double.
