You should know...

 Manners:

Handshake:

The way they greet and say goodbye is with a handshake, whether they are men or women. The handshake is used in both presentations and farewells. The handshake should be brief and with some
intensity.

Introduce himself / Identify yourself:

The way to identify yourself when greeting is by the last name, you do not say "Hello" as in other countries. When they answer the phone, they also identify themselves by their last name, they only use their names if asked.

Hugs and kisses:

Usually, hugs and kisses are reserved for circles of friendship and intimacy.

As a fun fact, in the Netherlands, touching your ear with your index finger means that you must answer a call or say that you are being called.
