Norwegians usually greet and take their leave of one another with a firm handshake - the firmer the better. There are few formal rules for greeting and no great importance is attached to greeting in order of rank, gender, etc.
It is important to note, however, that Norwegians are used to introducing themselves to one another, e.g. before meetings, during coffee breaks, at cocktail parties, so don’t expect your host to do the honours. It is common to exchange business cards after introductions have been made. Norwegians are egalitarian by nature and have a strong feeling of social equality. They will not be impressed by titles or name dropping.
During conversation, direct eye contact is very important in Norway. Norwegians are often perceived as being open and informal and discussions may assume a direct and personal tone even when the participants are not well acquainted.
