I applied through an employee referral. The process took 2 days.

The actual interview process seemed quite good. Alas, it was a complete waste of time. I applied for a job in Barcelona. They offered me the job, but then said the role was filled the day before, which is a bit weird already, I know. I told them to let me know about other openings there by voicemail, email, and speaking to the people running the Barca office. Instead, I just found out a few months later that they have been interviewing people for some new React positions in Barcelona. Weird, eh? There must be some problems with the recruitment system. The interview process is time-consuming for a company of this prestige, so be very careful with investing time into it, as I felt very, very let down after.

There was a React coding challenge at home. The face-to-face interview featured standard React and JavaScript questions. Typical competency questions included what you would do if you won a million dollars and how you fit into a new culture.
