Realizing this is not about the standard Schengen facility but specifically regarding the Portugal Job Seeker route. So FYI, the government has officially shifted the application process entirely to consulates.
The Update: This ultimately will be the law moving forward—you can no longer enter as a tourist and “manifest interest” for this specific category.
The Constraint: You must now demonstrate you are a “highly qualified” professional. This implies a specific higher education degree and stricter financial proof presented IN your country of origin (Consulate).
Just letting you know to prevent a wasted flight.
