I got selected in mastek thru the campus selections and that was 6 months
back. Our time the topics were
1. Shld GD  be the criteria for job selection.
2. Is govt policy of selling mill lands for building malls justified
and some other topics which were hot that time

But now obvoiusly they wld pick up some recent topics..
so be prepared anyways wishing u best of luck.
Only thng I wld suggest u is show the right attitude bcoz that what mastek is all abt.
One more thng is try to to initiate the gd and that is very important. 
It wld definitely be a + pnt
