Every application goes through the same four steps.
Find
Spainward reads job boards and company career sites in Spain and keeps the roles someone from abroad can actually take: the ones that sponsor, or that fit a visa route. See Which roles count as open to foreign candidates.
Prep
For each role it rewrites your CV and writes a cover letter, in English or Spanish, from your own facts. See How CV tailoring and cover letters work.
Apply
It fills in the company's own form and sends it. When a form asks something only you can answer, it stops and asks you. See When Spainward stops and asks you.
Track
It follows each application and shows you the replies, so you always know where each one stands.
