Do all the hostel rooms get booked within the first week of the online hostel booking for the SRM Kattankulathur campus? Which rooms get filled first?

Mostly first, second, third floors and so on will get booked faster as they r not as hot as compared to the top floor rooms. Try to book your room as fast as possible and try to come to your room a day or two before the other occupants to get your choice of bed( in case of sharing room)
