I just did another phone interview this morning (actually it was over Skype). I think I see another way that IM interviews are different from voice: the way previous utterances are saved. IM is different from voice communication because speech is ephemeral. Once you say something, it’s gone. Even if you’re recording the exchange, you can’t review the recording during the conversation itself. But with IM, you can always scroll back and see that there was a point you wanted to come back to. So time is handled differently with regards to IM. This isn’t a novel observation, but it was just something that struck me after this morning’s regular old voice communication.
