You can get interview calls for MS in old IITs/IISc. But the conversion rate for this is quite bad -- because most of the toppers are trained for question solving and not knowing research.
For your expected rank, as per last year NITC is possible- but in last round (NSR).

If job is a must now, you can consider joining. But if attending interviews is difficult then do not join. If I were you I would focus just on IIT interviews.
