A good interview implies saying the right things, but you'll also need to listen. Being a good listener implies:
avoiding prejudice
When we meet people for the first time, we make up our minds about them during the first two minutes. Because this happens subconsciously, there's not much you can do about it. Recruiters are obliged to look beyond denomination, race, sex, nationality..., but so are you.
showing interest in what the speaker is saying
A good interlocutor uses an open body language (e.g. arms unfolded, nodding...) and positive paralinguistic cues (saying things like mhm, I see, really?...)
being aware of speaker's feelings
Show empathy with what your interlocutor is saying.
clarifying and summarising
When the pace of the interview is slacking, a good recruiter will summarise what has been said and ask another question next. You can also do so if you want to recapitulate what you have been saying so far.
