What Sero screens for
relevant experience and ability to operate autonomously
Tailor your CV to the specific Sero role rather than sending a general one. Applications that mirror the language of the job description clear automated filters at a materially higher rate.
Mistakes that kill Sero applications
Don't send the same CV you sent everywhere else. At <50 people it's obvious, and it's the fastest rejection there is.
Lead with their problem, not your ambition. Sero is focused on is growing — show you understand that.
Most B2B applications get ghosted. A day-five follow-up can double your response rate.
