Clarify your message. It feels that you yourself don't fully believe what you saying. - Team Leader Nokia Employee Review

The R&D side of Nokia is highly focused on Finland. While I wouldn't say that there is a glass-ceiling for non-Finns as such, not being able to speak Finnish makes you somewhat of an outsider. You have to make an extra effort if you want to get ahead as a foreigner. Also, if you are not based in Finland, the situation can be very difficult. From persons I have spoken with who are based in e.g. Denmark, Germany, and in the US, there is a lot of resentment against the "Finnish mafia."
