One of my close friends applied for the lateral entry program at IIIT Hyderabad in 2018 and shared the experience of the entire process. Her examination center had students from Raipur and Bhilai regions. The total number of students in the hall was 70.
On average, there were 50 centers, and considering each center had 100 students, the total number of students who appeared for the IIIT Hyderabad Lateral Entry Programme was around 5000. In her examination center, only 45 students were shortlisted for interview, out of which only 37 students actually attended the interview.
