Software and data
The sector most comparison writing is based on, and the least representative. Public code, technical writing and specialist communities carry weight that a profile does not, and referrals through those communities are a normal hiring route.
Startup platforms are unusually relevant here because the sector is where salary and equity disclosure became conventional first.
Healthcare
Registration and licensing bodies matter more than any platform. Roles are frequently filled through specialist recruiters, professional bodies and employer systems rather than through open networks.
Public posting carries professional risk in patient-facing roles, which changes the calculation around content and visibility considerably.
Design and creative
The work is the credential, and a text profile cannot display it. Portfolios do the primary job, with referrals and community recommendation close behind.
General networks function mainly as a verification step: someone who liked the portfolio checking that the career is what it appears to be.
Finance and professional services
Closest to the model general networks were designed around: named firms, recognisable titles, sequential progression. The standard profile format describes these careers accurately with no adaptation.
Confidentiality norms are stronger than in most sectors, so visible job search activity carries more risk at senior levels.
Trades and skilled manual work
Hiring runs through local reputation, direct employer application and aggregators with strong location search. Certifications and a record of completed work matter more than any online profile.
This sector is largely absent from platform comparison writing, which is itself worth noticing when reading recommendations.
Education and academia
Institutional job boards and disciplinary channels carry most vacancies, often with formal application processes that no general platform touches. Publication record functions as the credential.
Academic hiring cycles are also slower and more structured than the platforms in this comparison assume.
Public sector
Formal application through official portals is usually mandatory, with structured criteria and scoring. Networking rarely shortens the process because the process is designed to prevent that.
Platforms are useful for finding out that a role exists and for understanding the organisation, not for influencing the outcome.
Marketing and media
One of the few sectors where public content genuinely functions as evidence, because visible audience-building is close to the job itself.
This creates a distortion in the wider advice landscape: people in this sector write much of the platform advice, and content strategies that work for them transfer poorly to sectors where posting is not the work.
