No, first-year B.Tech students do not get a single occupancy hostel room. In fact, no government-funded Institute of National Importance will provide you a single occupancy room or AC room at least in the first year.
The rooms are very clean and if you keep them that way, then you won’t have any problem. The rooms are spacious enough as well. In the first and second year sharing rooms will eventually make your group studies more fun. In the third and fourth year, only you will get single occupancy rooms.
