I applied and waited a while to hear back from them. After they contacted me I was invited to a meeting day and after that got an email offering me the position.

Finnair requires that all FA are able to swim, so you'll need to be able to swim 50m with no stops to start the recruitment process. There was a short interview held in the poor area before you swim. After the swim test, you'll be invited to the next step in the recruitment process. The interview process was smooth.
