After applying for the position, I got a phone call for the phone interview, and then I went through two language tests. Finally I was offered a chance to have the final face-to-face interview, which I didn't finish yet.

Applied online, then the next day received email to complete a video interview online. A couple days later did a phone interview asking some general behavioural questions, a week later did a language test over the phone in two different languages. Few weeks later had an in person interview, then waited about two-three months before got offered the job

Many stages. From initial application there was a telephone interview, language tests, and an in-person interview before the job offer was presented. The interview questions were largely situational to try to gauge how you would react in certain situations.
