Show Interest

Put your hand up for a role. Idempotent.

Why a profile is required

422 for an account with no user_profiles row. What a company receives is a list of people, and a person with no profile is a line that says nothing: no name, no headline, no skills, nothing to decide on. Sending that is worse than sending nothing, because it costs the company a click to find out it was empty and it tells the candidate their interest was registered when in practice it cannot be acted on. The message names the fix and the client links to it.

Note what is NOT required: a PUBLIC profile. A private profile 404s for strangers, but expressing interest is a deliberate, per-role disclosure to one company, and requiring publication would make "let this one employer see me" impossible without also making "let everybody see me" true. The interest is the consent, and it is scoped to the role it was given on.

Why you cannot show interest in your own role

409, because it is a category error rather than a permission problem, and because a company appearing in its own candidate list would be the first bug reported.
