Beware if they ask you to travel to their Barcelona HQ! Terrible experience, almost a scam! I had to pay for everything upfront and then it took three months for them to reimburse me. If I hadn’t sent many follow ups I wouldn’t have received my money. Also their process was not clear, HR said three stages and then kept adding new ones without notice. Such a waste of time. Certainly a company that doesn’t care about your time - and even worse, your money-. Hiring manager welcomed me to the team and then took her word back. Not serious at all.
