That's interesting, that you are from India - in Germany we'd actually phrase the question exactly the same way: where do you sit? Some might also ask where is your desk? It is a casual way of asking that depends on knowing the person you're talking to or at least having been introduced to them and being aware that they are co-workers and roughly your same level. But that seems to be the context you're describing. In a friendly atmosphere politeness is mainly a matter of tone of voice.
