The translation agency  Tetrapod Translations offers you different modes of interpreting:

• simultaneous interpreting:

The interpretation occurs while the source language speaker speaks, as quickly as the interpreter can formulate the spoken message to the target language. Simultaneous interpretation is used in various situations such as business conferences, graduation ceremonies, any situation where there is not pause between each statement allowing time for the interpreter to relay information to the audience.

• consecutive interpreting:

In consecutive interpretation, the interpreter speaks after the source-language, -text speaker has finished speaking; the speech may be divided into sections.

Normally, the interpreter sits or stands beside the speaker listening and taking notes as the speaker progresses. When the speaker finishes speaking or pauses, the interpreter consecutively renders the message in the target language, in its entirety, as thougt he or she were making the original speech.

• liaison interpreting:

Liaison interpreting involves relaying qhat is spoken to one, between two, or among many people. This can be done after a short speech, or consecutively, sentence-by-sentence, or as chuchotage (whispering); aside from note taken then, no equipment is used.
